Okay.
Here is a problem that I have just made up which brings together percentages and rounding concepts:
£600 is to be divided as follows:
Abigail is paid 75% of £600
Emma is paid 4% of £600
Michael is paid 2.5% of £600
Daniel is paid 18.5% of £600
How much money in pounds is each person paid ?
Give two reasons why it would not be a good idea to round the
percentages to the nearest whole number before doing the calculation
and give the figures involved in what would happen.

A good place to start would be to convert the percentages into a decimal format.
So what is 75% as a decimal ?
(75/100) = 0.75
....
Now what can you do with that result using a calculator to help?

hi steveb is it 7.5 then
Offline
No that is not what I meant. 0.75 is what I am calling 75% in decimal format.
Now we need to work out 75% of £600.

what do i do then

Do this on your calculator:
0.75 x 600 = .....
Offline
0.75 x 600 = 450 now what

Now what is 4% of £600 ?
Offline
0.4 x 600 = 240
Offline
I am afraid that is not quite right.
4% is not 0.4 it is 0.04
Offline
2.5 x 600 =1500
Offline
No 2.5 % is 0.025 not 2.5

what am i doing wrong then

With the 4% of 600 one you should have done this:
0.04 x 600 = .....
You did:
0.4 x 600 = .....
Offline
With the 2.5 % of 600 you did:
2.5 x 600 = 1500
It was supposed to be:
0.025 x 600 = 15
Offline
0.04 x 600 = 24
Offline
What is 18.5% of £600 ?
Offline
0.025 x 600 = 15
0.185 x 600 = 111

Good right so can you gather those answers together to answer the first part of the question:
Abigail is paid 75% of £600
Emma is paid 4% of £600
Michael is paid 2.5% of £600
Daniel is paid 18.5% of £600
How much money in pounds is each person paid ?
Offline
