I'm not sure what the question is.... do you have to work out the different percentages of those values e.g. 1% of 60 etc?

Well to find 1% of something you have to move the decimal place two spaces to the left so for example 1% of 60 becomes 0.6, 1% of 28 becomes 0.28 and 1% of £5.40 becomes £0.54 or 54p

Then to find all the other values such as 2% 3% etc all you have to do is multiply the value you found for 1% by these numbers

grid is so hard wish i could show to you but like i said 1 to 10 down left side & at the top diffrerent percentage eg 100%50%25% so on then down the grid spead out is 60kg 28cl

right so with the 60 kg, which percentage does this come under and which number from 1-10 is it by?
07 June 2011

Ok so I think we just ignore the 1-10 bit and simply assume that it just refers to the different values and then with the 60 under the 50% column we know that if 50%= 60 then 100%= 120 and 25% = 30
07 June 2011
And then for the 28 under the 10% that means that for 50% all we have to do is multiply 28 by 5 so that we get 140 under 50%
07 June 2011
Then we double 140 find out the value for 100% = 140x2 = 280
07 June 2011
And then halve the 140 to find 25% so 25% = 140/2 = 70
