Math 8 Q1 (Pre-Algebra) / The Number System

Which of the following is a rational number between 5 and 5 1/4?(1 point)

5 2/5
5 Start Fraction 2 over 5 end fraction

26−−√
start root 26 end root

5 1/7
5 Start Fraction 1 over 7 end fraction

5 1/3

5 1/3

To find a rational number between 5 and 5 1/4, we can find the average of the two numbers.

Add 5 and 5 1/4 together:

5 + 5 1/4 = 5 + 20/4 = 20/4 + 20/4 = 40/4 = 10

Divide by 2 to find the average:

10 ÷ 2 = 5

Therefore, 5 is a rational number between 5 and 5 1/4.
