Question

write a rational number equivalent to -5/-7.

Answer 1

Here is your answer:-10/-14

Answer 2

Hey pal!

Here's your answer>>

To find a rational number equivalent to any other rational number (say m/n), we should multiply or divide both the numerator and denominator with the same rational number (say s). 

Which means that, m/n × s/s = ms/ns (which is an equivalent rational rumber of m/n) 

So, now moving to your question>>

A rational number equivalent to -5/-7 

First, bring the number to the standard from, which means that the denominator should be a positive integer and not a negative one. 
-5/-7 × -1/-1 = 5/7 

Next, divide 5/7 with the same rational number. Here, I am taking 2. 

5/7 × 2/2 = 10/14 

Hope helped!!
