Question

Find the percent of each number. 64% of 75 tiles. 20% of 70 plants. 32% of 25 pages. 85% of 40 e-mails. 72% of 350 friends. 5% of 220 files.

Answer 1

Clearly, wether we're talking about tiles, plants, pages, e-mails, friend or files, the math won't change! :)

Percentages are just special fractions, since they have denominator 100. So, for example, 64% of 75 is given by

`75* (64)/(100) = 75/ 100 * 64 = 0.75* 64=48`

So, you divide the number by 100 and then you multiply by the percentage you want. As a last example, 20% of 70 is

`70* (20)/(100) = 70/ 100 * 20 = 0.7* 20=14`

And so on with all the others
