Remember that

The percentage can be calculated by dividing the value by the total value and then multiplying the result by 100.

P=(value/total value)*100

we have

P=40%

total value=70

value=?

substitute

40%=(value/70)*100

40/100=value/70

value=0.40*70

value=28

therefore

The answer is 28
