Question

What is 50% of `2/3` of $1.20?

Answer 1

It is `$0.40`. See explanation.

Explanation:

To calculate the amount you have to calculate:

`50%xx2/3xx1.20`

First step is to change all factors to numbers. The percentage can be written as the fraction with denominator `100`, so the expression becomes:

`50/100xx2/3xx120/100`

The first fraction can be reduced by the factor `50`, so it becomes `1/2`, the last fraction can be reduced by `20` to become `6/5`
So we get:

`1/2xx2/3xx6/5=2/5`

Now to change this number to the currency we have to change it to a fraction with denominator `100`:

`2/5=(2xx20)/(5xx20)=40/100`

Finally we can write that the sum is `40/100` of a dollar. That is `40` cents.
