Question

How do you write 1.12 as a mixed number

Answer 1

$1.12=1\dfrac{12}{100}=1\dfrac{3}{25}$

Answer 2

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
