£30 as a percentage of £90 can also be written as 30/90. This changes to 10/30 if divided by ten and 1/3 when divided by 3. 1/3 as a percentage is 33%

Divide 30 by 90 and simplify to give 1/3 . Then multiply that by 100 and it will give 33.3% which is the answer.

30/90 = 1/3 = 0.333 = 33%

Hi Carolyn!


With this question, the best way to work out £30 as a percentage of £90 would be to do 30 divided by 90 because 30 is the part and 90 is the whole. This will then give you 0.33… as a decimal. To then turn this into a percentage, we multiply by 100. Giving us the answer of 33.33… (reoccurring).


Hope this helps!

  1. 30 divided by 90 = 1/3
  2. Now you multiply 1/3 times 100 = 33.33%( The answer will be a recurring one so you need to keep it up to 2 or 3 decimal places.

In order to express any value as a percentage of another, you must divide that value by the original and multiply by 100.

In this case, the value is 30 and the original is 90.

So,


30 / 90 = 0.333333...


0.333333... x 100 = 33.3%


Therefore £30 as a percentage of £90 is 33.3%
