Question

George uses the diagram below to help determine 30% of 60. Which expression could George have used?

Answer 1

60 *(30/100) works too

Answer 2

`(3)/(10)* 60\text{ or }(30)/(100)* 60`

Explanation:

Given expression,

30% of 60,

We know that,

Convert percentage to fraction :

`a\% =(a)/(100)`

Thus,

`30\% = (30)/(100)=(3)/(10)`

So, 30% of 60 =
`(3)/(10)* 60`

Which is the required expression.
