Re: Mandy Jane's Corner

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.

Re: Mandy Jane's Corner

Are you able to do a problem like the one in my previous post, or is that one too difficult for you at the moment ?

Re: Mandy Jane's Corner

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?

Re: Mandy Jane's Corner

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.

I am afraid that is not quite right.

4% is not 0.4 it is 0.04

Re: Mandy Jane's Corner

With the 4% of 600 one you should have done this:

0.04 x 600 = .....

You did:

0.4 x 600 = .....

Re: Mandy Jane's Corner

With the 2.5 % of 600 you did:

2.5 x 600 = 1500

It was supposed to be:

0.025 x 600 = 15

Re: Mandy Jane's Corner

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 ?
