Express 3/4 as a rational number with denominator: -80

Solution:

Given, the rational number is 3/4

We have to express the rational number with -80 as the denominator.

If the numerator and denominator of a rational number are multiplied or divided by a non-zero integer, we get a rational number which is said to be equivalent to the given rational number.

Considering 3/4,

To make the denominator as -80, we have to multiply the numerator and denominator by (-20)

3/4 = 3 × (-20) / 4 × (-20)

= -60/-80
