Firstly we write 1.12 in fraction form instead of decimal, therefore, it becomes:\
1 12/10 ( One whole number, 12 over one hundred)
Next we simplify the denominator and numerator, in this case, we divide both by four (4). Therefore we now have 1 3/25 ( also described as one whole number three over twenty five ) This is our final answer, the mixed fraction equals 1 3/25 .
