Question

A flight from Melbourne to Sydney was discounted from $500 to $100. By what percentage was it reduced?

Answer 1

100 of 500 is 20%

Explanation:

100 of 500 can be written as:

`(100)/(500)`

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

`(100)/(500)` ×
`(100)/(100)`

`=((100*100)/(500) )` ×
`(1)/(100)=(20)/(100)`

Therefore, the answer is 20%

If you are using a calculator, simply enter 100÷500×100 which will give you 20 as the answer.
