How do you solve: 21 11/12 plus 17 5/12

GarryVolchara [31]

The problem is $21 \frac{11}{12} + 17 \frac{5}{12}$

Add the whole numbers

$21 + 17 = 38$

Match up the fractions and make sure the denominators are the same (they are)

$\frac{11}{12} + \frac{5}{12}$ $= \frac{16}{12}$

Break down the fraction

$16$ ÷ $12 = 1 \frac{4}{12}$

Reduce-You need to find a common factor for both the numerator and denominator

$4$ ÷ $4$ $= 1$

$12$ ÷ $4 = 3$

Combine everything

$38 + 1\frac{1}{3} =39 \frac{1}{3}$

Answer: $39 \frac{1}{3}$
