Given below are three pairs of numbers Pair 1: (-10) and (-9)
Pair 2: 5.91 and 5.92
Pair 3: 2/3 and 4/5
In which pair(s), can a rational number be found between the given numbers?

in the 3 pairs we can find a rational number.

Step-by-step explanation:

A rational number can be any number written as a quotient of two integers.

The rational numbers have a finite number of decimals after the point (or periodic)

a) (-10, -9)

between those two numbers we have, for example, -9.5

and we can write this as:

-9.5 = 95/100

b) (5.91, 5.92)

between these numbers, we have the number 5.915

and we can write it as: 5.915 = 5915/1000

c) (2/3, 4/5)

between 2/3 and 4/5 we have for example the number 3/4.

because 2/3 = 0.66

4/5 = 0.80

a number between those two is 0.75 = 3/4.

answer: 88
