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:

  1. Multiply £1.20 by 100 - giving us the amount in pence - 120p is what we get.
  2. 57/120 will give us a decimal which can be changed to percentage in a next step.
  3. We will multiply 57/120 by 100 which will give us 47.5%

£1.20 = 120p


57p/120p = 19/40


19/40 = 0.475


0.475 x 100 = 47.5


==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%.

convert the £1.20 into pence, so both items are pence. Then either do long division and divide 120 into 57 or on a calculator do 57/120 and then x 100 to make it a %

Answer: 47.5%


Explanation:

First of all, you need to change either of the numbers to the same unit, you can either do this by converting:


57p to £0.57

or

£1.20 to 120p.


Now we can divide the smaller number by the bigger number to receive an answer of 0.475.

Following this, we need to convert this decimal into a percentage and we can do this by multiplying by 100 and thus we get an answer of 47.5%

Do 57/1.20 which is 47.5%

£1.20= 120p

hence 57p = 47.5% of £1.20 as 57/120 X100= 47.5%

So starting with a basic rule. For calculating percentage, both the quantities need to be in the same units. This rule actually follows from fractions, of which percentages are just an extension.

So converting both in pence units, we have 57p already and £1.20 as 120p, since 1 pound has 100 pence to it.

% = (57/120) x 100

= 0.475 x 100 = 47.5%

So, 57p is 47.5% of £1.20

first, convert £1.20 into pennies, by multiplying 1.20 by 100 (as there are 100 pennies (p) in a pound (£)).

please note that there are 100 pennies in a pound.

£1.20x100£ per p=120p


Now, find how many 57 pennies go into 120 pennies (57 divided by 120)

use a calculator for this

you should get 0.475.


This has now given you your fraction between the two values given in the question.


to convert from a fraction to a percentage we now multiply by 100.

This gives us 0.475x100 = 47.5%.


We can now conclude that 57p is 47.5% of £1.20.




Please note that percent (%) is said as per-cent (as in out of 100)

mathematically, we write this as multiply by 1/100 (x1/100) where x means times.

Hi, I would set this out:


1.20 = 100% , therefore 1% = 0.012


I would then do: 0.57/0.012 = 47.5%

57p

divided by

120p


= 47.5%

For this you would do it as any other percentage question. You would do 57/120 x100 and would get an answer of 47.5%

To find how much 57p is as a percentage of £1.20, we will see how much 57p is valued in comparison to £1.20, so we will need to write this as a fraction. First, we need to make sure both numbers have the same currency or "units", so we will convert £1.20 to 120p as £1 contains 100 pence and £0.20 is 20 pence.


This is how it looks, 57/120. To convert from fractions to percentages, we can use a division method or use a calculator to divide this, we then get 0.475. To convert this to a percentage, we multiply the number by 100. The final answer is 47.5%.

Firstly, change the £1.20 to pence (120p).

Find 57p as a percentage of 120p by dividing 57 by 120 then multiply by 100.
