÷5 ÷ 5
Answer = 3 / 4
Note: 75 / 100 is called a decimal fraction and 3 / 4 is called a common fraction !
Example: Convert 0.625 to a fraction
Step 1: write down:
0.625 / 1
Step 2: multiply both top and bottom by 1,000 (3 digits after the decimal point, so 10×10×10=1,000)
625 / 1000
Step 3: Simplify the fraction (it took me two steps here):
÷ 25 ÷ 5
625 / 1000 = 25 / 40 = 5 / 8
÷ 25 ÷ 5
Answer = 5 / 8

Step 1: write down:
0.35 / 1
Step 2: multiply both top and bottom by 100 (2 digits after the decimal point so that is 10×10=100):
