x=15/72
x=5/24

hope it helps you

Answer 2

Answer-The other number is $\frac{5}{24}$

Explanation-

Given-Product of two rational numbers is $\frac{-15}{28}$.

One number is  $\frac{-18}{7}$

Find the other number.

Solution-In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. For example, $-3/7$ is a rational number, as is every integer.

Let the other number be x

According to the question

$\frac{-18}{7}\times x=\frac{-15}{28}$

$x=\frac{-15}{28}\times \frac{-7}{18}$

$x=\frac{5}{24}$

Hence, the other number is $\frac{5}{24}$
