Yes that is correct. Good.
Let's go back to division: 3.9 divided by 100 ?
Offline
3.9 ÷ 100 = 0.039 am I right?
Offline
Correct. Good.
Right do you want to return to ratios or carry on with multiply/divide by 10 and 100 ?

Hi steveb mandy here could you go back to ratio and give me some sums to do for tomorrow please?
Offline
Okay. Here is a question to do with ratio in a different context:
Let us suppose that there is a sum of money £120.00 (120 pounds) and it has to be shared in a 1:2 ratio
For every 1 pound that Edward gets Sarah is given 2 pounds. So the ratio amount given to Edward: amount given to Sarah is 1:2
Calculate how much money in pounds Edward and Sarah should be given to make this happen.

Hi steveb mandy here the answer to your question are
Q1 = 92 x 100 = 9200
Q2 = 3.4 ÷ 10 = 0.34
Q3 = 0.17 x 10 = 1.7
Q4 = 72 ÷100 = 0.72
Q5 = 8.6 x100 = 860
Q6 = 0.76 ÷10 = 0.076
Q7 = 0.13 x 100 = 13
Q8 = 25 x 10 = 250
Q9 = 0.03 x 100 = 3
Q10 = 4.5 ÷ 100 = 0.045
Am I right with all of these?

All ten of those are correct. Well done.
Looks like it's back to ratios then.

Hi steveb mandy here just to say yes back to ratio then? I will have a look at the question you left me ok? I will be back on here at 2.30pm today see you then?
Offline
Hi Mandy. Did you manage to do the ratio question ?
Offline
Hi steveb mandy here i had a look at the ratio question you left me to do? I am finding this it hard but want to have a go at it on my own? So could I come back to you at 4.00pm and I will let you know how I got on ok?
Offline
Okay let's do that. I will log on again at 4pm.
Offline
Mandy, how have you got on with that question? Are you still stuck?
Offline
Hi steveb mandy here i am still working on the question you gave me ok can I do. It and send you the answers tomorrow to you if ok? What else can I do as well please?
Offline
Tricky. If I give you more questions on ratio then that will simply add to things that you don't know how to do.
Bob gave you some exercises as a sort of test of maths that you have recently done. You could do those.
Offline
Hi steveb mandy here ok I will do the test bob gave me ok? So I will be on here tomorrow at 2.30pm if ok with you? Send me message back please?
Offline
Yes that's okay. See you tomorrow.

Hi bob bundy mandy here how do you think I am doing with my maths then?

Hi steveb mandy here could we leave ratio for now and do finance like overtime pay please?
Offline
Hello Mandy. We could do something on finance/overtime pay. I have not got anything prepared, but we could discuss the topic
and perhaps invent an example of some figures such as a rate of pay, a number of hours worked and the number of hours of
overtime as well as a rate for that overtime. In others words to do an example of that we need some figures such as:
£ 6.50 - hourly rate
39 hours - normal full time hours
3 hours overtime
overtime paid at time and a half
The above is just something that I have thought of off the top of my head you understand (randomly) and the figures will not
necessarily be either realistic or "nice round numbers" then again in real life examples the figures will only rarely be nice and round.
Offline
Hey steveb mandy here how would you work out the overtime pay then?
Offline
Sorry about that my computer crashed.
Now there are a few points I should make here. First I am not a qualified accountant so I do not know precisely how all of these
financial calculations would work for example I do not know about how the income tax and national insurance would be added
because these are things that apply to a particular individual for starters not to mention the fact that I have never been formally
taught how to do these calculations.
Nevertheless let us ignore the complication of income tax and national insuance taken off for now and work out the gross pay
given to the employee. Can you using common sense work out what we might do as a calculation to work out the employee's
pay in the example in post # 996 ?
Offline
Hi steveb would you do 3 x £6.50 am I right?
Offline
Right here is what I would do to work out the gross pay:
£ 6.50 x 39 to get the amount without overtime added.
Then £ 6.50 x 3 x 1.5 to get the overtime pay
Then add the two so Total Gross Pay = (£6.50 x 39) + (£6.50 x 3 x 1.5)
The use of the 1.5 comes from the "time and a half" bit where we are adding 50%
Now I was trying to explain something like this in the topic on percentages. So you can see here that a basic knowledge of
percentages is essential to understand the calculation above.
