Question

Alice has solved 28 problems of the 70 problems assigned. What fraction (in

lowest terms) of the problems has been completed ?

Answer 1

Answer: 2/5

Explanation:

The fraction of the problems that Alice has solved is 28/70.

We can divide the numerator and denominator by 2 to get the fraction 14/35.

We then can divide the numerator and denominator by 7 to get the fraction 2/5.

We cannot further simplify this fraction, so 2/5 is the fraction of the problems solved in lowest terms.
