Question

Dinh finished part of her reading homework, reading 20 of the 25 assigned pages. Explain how to find the percent of her reading homework that Dinh completed.

Answer 1

Dinh read 20/25 pages, simplified by dividing by common factors this equals 4/5.
Because percentages are measured out of 100 divide this number by 5 (the denominator) and you are left with 20. Then divide by 4 (the numerator) and you are left with 80.
Therefore, the percentage of assigned pages read equals 80%.
