Write the decimal number as a fraction
(over 1)
1.12 = 1.12 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator = 1.12 × 10 × 10 × 10 = 1120
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / denominator = 1120 / 1000
Simplifying our fraction
= 1120/1000
= 28/25
= 1 3/25
