Answer
The pair of fractions is not equivalent.
Work Step by Step
The least common multiple of the denominators of the fractions is 40. Adjust the fractions based on the least common multiple. For the first fraction, multiply the numerator and denominator by 5.
$ \frac{7}{8}\times \frac{5}{5}= \frac{35}{40}$
For the second fraction, multiply the numerator and denominator by 4.
$ \frac{9}{10} \times \frac{4}{4}= \frac{36}{40}$
Compare the two fractions
$\frac{35}{40}\ne\frac{36}{40}$
The pair of fractions is not equivalent.
