Hi Mandy
I have decided to give you just ONE question which is one I have already mentioned:
1 foot = 12 inches
1 inch = 2.54 cm
How many cm are there in a foot, preferably to 2 decimal places?
Do not spend too long over that. If you cannot answer within 5 minutes just guess the answer.
You can use a calculator for that one, but tell me the method that you used.

Hi steveb mandy here the answer to the question are
Q1 = 7m into cm = 7x100 =700cm
Q2 = 60m into cm = 60x100 = 6000cm
Q 3 = 5000cm into m = 500 ÷ 100 = 5m
Q 4 = 400cm into m = 400 ÷ 100 = 4m
Q 5 = 20.4m into cm = 20.4 x100 = 2040cm
Q 6 = 9643c into m = 9643 ÷ 100 = 96.43m
Are they right or not?

All correct well done (except Q3). Try the one above if you haven't already.
Actually Q3 was 5000 /100 = 50 m
Anyway you have got the hang of it. Good.
I will go away for a few minutes for you to try the feet/inches/cm one.

The answer to the question how many cm are there in a food preferably to 2 decimal places? Is the answer 2.54 x 12 = 30.48cm is this right or not?
Offline
Correct. 30.48cm is 12 inches.
Right are you able to work out how many feet there are in one metre ?
Or if it is easier how many inches are there in 100cm ? (Then how many feet in 100cm?)

Hi steveb how many inches are there in 100cm the answer is. 12÷100cm = 0.12. Am I right or not?
Offline
No 100 / 2.54 = 39.37 inches approx.
Notice that 39.37.. x 2.54 = 100 cm
You can if you like divide by 12 to get the amount of feet in one metre.

I am getting 3.28 feet in a metre to 2 decimal places.
Not sure if this helps, but imagine a 1 metre long ruler - now imagine 3 foot long (12in or 30cm)
rulers in a line. The metre ruler is a little bit longer than the 3 one foot long rulers.

Could you give me some to do for tomorrow please?

One thing you might like to consider is:
An object is said to weight one stone exactly.
1 stone = 14 pounds
1 kg = 2.20462 pounds
How much is one stone in kg ?
By kg or Kg or KG I mean kilograms that is to say 1000 grams.
"kilo" usually means 1000 of something.

A few on metres, feet, inches and centimetres:
(1) Convert 5 metres into inches.
(2) Convert 20 inches into centimetres
(3) Convert 15cm into inches.
(4) Convert 1 foot into metres
One on weight:
(5) Convert 1 pound into kg (use the information in the previous post to help with this)
Doing Q5 might help with the question:
(6) Convert 1 stone into kg.

Could you give me some work on m into cm foot into inches and could I have some work on stone intimate kg and pounds as well please?
Offline
Ok steveb I will do these for you tomorrow ok? Buy for now

Another question about feet, inches, cm and metres is:
A person is said to be 5 foot 9 inches tall exactly.
(1) How many inches is the person is just using inches ? (Hint: 12 inches equals one foot.)
(2) Now convert this into centimetres. (Remember: 1 inch = 2.54 cm)
(3) Now convert this into metres.
(4) You could also put this in the form of metres and centimetres.
(I mean by that to put 100cm as 1 metre and give the rest as centimetres.)

By kg or Kg or KG I mean kilograms that is to say 1000 grams.
"kilo" usually means 1000 of something.
I am going to do this as an example:
1 stone is 14 pounds
Therefore we want 14 pounds converted into kg.
If you divide 2.20462 pounds by 2.20462 you get 1 kg.
So divide 14 pounds by 2.20462 using a calculator and get:
6.350300732
Obviously this needs to be rounded because it is more accurate than we could
possibly have measured so I am going to round it to 6.35 kg in one stone.
(I have found out from another source that it is 6.35029 - I am not sure which is more
accurate and it does not matter because in practice you would not need to be that
precise except in engineering/scientific precision situations.)

A few on metres, feet, inches and centimetres:
(1) Convert 5 metres into inches.
I am also going to do this one:
5 metres = 500 cm
To convert to inches I need to divide by 2.54
500 / 2.54 = 196.85 inches (to 2 dp.)
or 197 to the nearest inch.

Hi steveb mandy here i have tried to send you an email but I can't get it to send you and I don't know why? Hope you get this ok? Send me message back on here to let me know please?
Offline
I have received some emails from you today.
I have just replied with questions and answers from the 17th May and
the 21st April, which were sent as answers on 20/21 June.
They are long emails so if needed I can post here, but if you now have them
then great.
Offline
hi i don't know why the email are not going thought quitley is it the weather or not? i have got question ok thanks.
Offline
I don't think the weather has had any effect on the system (overheating etc.).
The thing that I thought was the weather turned out to be caused
by roadworkers making an error causing a connection failure.
I received the 2 emails where you asked for the questions only too
late and had just sent the answers and questions emails.
After a pause of 5 minutes or so I sent the questions only.
It may still help you to try to do those since you have the answers now
in case you are stuck with them. Notice also that I have answered two
of the recent maths exercises as examples in case you were stuck on them
(see above).

(2) Convert 20 inches into centimetres
I am getting:
20 x 2.54 = 50.8 cm
It may be helpful to think of a ruler (eg. 30cm, 15cm etc.)
to get a rough idea when doing these to make sure you don't
do the calculation the wrong way round.
Offline
I have thought of another conversion you might like to do:
ounces to grams and grams to ounces
eg. 1 ounce = 28.3495 grams (perhaps round to 28g)
(use exact figure if more accuracy is needed then round at the end)
So for instance how many grams in 6 ounces ?
How many ounces is 100 grams ?
Be careful to make sure you have got that right if needed for a cooking
recipe and/or something important.

Hi bob bundy mandy here i have sent you an email ok. I am not sure what emails have gone through and which ones have not been received by steveb as I am very confused with it? Can you help me out please?

I did wonder whether the length of an email had anything to do with it (eg. 10K rather than 3K for instance).
None of the emails are especially big in today's terms when 10K = 1024 x 10 = 10240 bytes for instance is small compared
to let us say the RAM in a computer let us say 2GB for instance which is 2147483648 (2 x 1024 x 1024 x 1024).
However I remember from something that happened some time ago (maybe a year or 2) where I had to send a large attachment
(50+MB approx ???) that someone had asked for where my email system warned me that it couldn't send it and I received a delivery
failure message. To give an idea of scale this is about 5.24 million bytes more than 5000 times the size of a 10K email.
You should really get an error report or delivery failure message occur every time something you send does not get through.
However maybe some software is set up not to do this sometimes, or maybe there is some other problem.
My experience today and recently is that all of your emails are getting through as far as I know. You have sometimes spelled
my email address wrong, but your computer will put the address in for you in a reply and may help you even when sending a new
message depending on what you are using to send them with and how good the software is.
