Use long division to convert the rational number to its equivalent decimal form.

0.25

0.125

1.25

2.5

Since the rational number is not given, then I would just do the reverse solution and convert the decimal form into the rational form. To do this, divide the numbers in the decimal side with the corresponding largest place value.

A. 0.25 = 25/100 = 1/4

B. 0.125 = 125/1000 = 1/8

C. 1.25 = 1 + 25/100 = 1 1/4 or 5/4

D. 2.5 = 2 + 5/10 = 2 1/2 or 5/2

I go to the same school, the fraction is 1/8
