You have to consider 1.20£ is 100 and find the percentage of 57 pence. So it should come as .57 as 1.20 has 2 decimal points. you divide 57 by 120 and multiply by 100.
57/120x100 =47.5%

First you need to write the 57p so it is in the same form as the £1.20. Therefore the 57p would be written as 0.57.
Then you need to write 0.57/1.20 (0.57 divided by 1.20) to work out what 0.57 is as a proportion of 1.20. The answer to this is 0.475.
Finally, you multiply 0.475 by 100 to give the final percentage. 0.475 x 100 = 47.5.
So, 57p as a percentage of £1.20 is 47.5%.
First make sure we use the same units! Convert £1.20 into 120p
Second 57 divided by 120 is 0.475
Multiply by 100 to get a percentage = 47.5%
57p
divided by
120p
= 47.5%

Hi, I would set this out:
1.20 = 100% , therefore 1% = 0.012
I would then do: 0.57/0.012 = 47.5%

hence 57p = 47.5% of £1.20 as 57/120 X100= 47.5%
57p divided by 120p (£1.20) will give you the answer in decimals which is 0.457, multiply by 100 for the answer in percentage: (57/120) x 100 = 47.5%
Percentage comes from "per cent" meaning out of hundred.
So you want the answer as a number less than hundred.
1) you first change the numbers into the same unit (pence) so £1.20 becomes 120p
2) you put the numbers into a fraction as 57/120
3) this gives you 0.475
4) to change this into a percentage, the final step is to multiply by 100 to give 47.5%
Firstly, we need to convert £1.20 into pence, so 120p, then we simply type in the calculator 57/120 *100

Hi Miss Ryan!
Lets begin by remembering what a percentage is? A percentage can be a portion of an amount. If we have 100% of an amount then we have the full amount. For example if we have 100% of a chocolate bar then all the chocolate is ours. If we have 50% of a bar then we have half the chocolate bar because 50 is half of 100. We can use this equation to help solve the question
Here are a number of steps I would use to find the percentage:

You need to convert both amounts into either pounds or pence. I will choose pence and then divide 57p by 120p and multiply the answer by 100.

Click here to view my profile and arrange a free introduction.First turn the money into a fraction - we want to find 57/120 which is 0.455.
We then multiply that by 100 to find the percentage - 0.455 x 100 = 45.5%
A quick way to solve this puzzle is to divide 57 by 120, and then times by 100.
So, (57/120)*100 = 47.5.
57 is therefore 47.5% of 120.
To elaborate, we have to view £1.20 as 100% in this equation.
Then, we can use 'x' to represent the value that we're looking for.
So:
100% = 120
x% = 57
Therefore
100% / x% is the same as 120/57.
Then, take the inverse:
x% / 100% is the same as 57/120.
Then take the 100% to the RHS (Right hand side) and you have:
x% = (57/120)*100 = 47.5
