3/20 ---------- ------------

Hi Steve mandy here I have done the maths home work. Sent you and bob buddy an email hope you got it? let me know please

SteveB · 2014-08-25 00:11:38

I have sent an email reply you with some marking. You are doing very well. Be careful about the fact that you tend to multiply by 1000 rather than 100 for some of the percentages. If you have something like 0.625 then the percentage is 62.5% not 625% for instance. We need to build up your intuition so that you know when you have made this mistake. However very good progress and good use of technology there with the spreadsheet. A lot of maths can be done on spreadsheets.

The latest set of questions are as follows:

Fraction Decimal Percentage

4/5 --------- -----------

1/12 --------- -----------

6/7 --------- -----------

1/3 --------- -----------

---------- 0.65 -----------

---------- 0.16 -----------

---------- 0.55 -----------

---------- ---------- 60%

---------- ---------- 40%

---------- ---------- 20%

---------- ---------- 80%

My apologies by the way about 1/12, 6/7 and 1/3
I realise that these need rounding.
I should try to round them to 2 decimal places if you can.
See if you can format the text in the spreadsheet,
but don't worry if you can't.

1/8 = 12.5% = 0.125

3/8 = 37.5% = 0.375

5/8 = 62.5 % = 0.625

52/200 = 26 % = 0.26

44/400 = 11 % = 0.11

55/500 = 11 % = 0.11

7/8 = 87.5 % = 0.875

7/40 = 17.5 % = 0.175

27/40 = 67.5 % = 0.675

are these right let me know please
