Question

Express $\frac{-3}{7}$ as a rational number with

numerator = $-15$

Answer 1

To make the numerator $-15,$ we need to use concept of equivalent fractions. Equivalent fractions are those fractions in which numerator and denominator are multiplied by the same non zero number.

$\frac{-3}{7}=\frac{-3\times 5}{7\times 5}=\frac{-15}{35}$

So, $\frac{-3}{7}$ with $-15$ as a numerator is $\frac{-15}{35}.$
