Question

Resolva:

5/12 + [2-(1/3 x 3/5) : 1/5]

Obs: A barrinha (/) é aquele tracinho - da fração.

Answer 1

$\frac{5}{12} + [ 2 - ( \frac{1}{3} . \frac{3}{5} ) : \frac{1}{5}] \\ \\ \frac{5}{12} + [ 2 - \frac{3}{15} : \frac{1}{5} ] \\ \\ \frac{5}{12} + [ 2 - \frac{3}{15} . \frac{5}{1}] \\ \\ \frac{5}{12} + [ 2 -1] \\ \\ \frac{5}{12} + 1 \\ \\ \frac{5 + 12}{12} \\ \\ \frac{17}{12}$

Answer 2

5/12 + [ 2 - (1/3 x 3/5): 1/5]
5/12 + [ 2 - 3/15 : 1/5]
5/12 + [ 2 - 3/15 . 15/3]
5/12 + [ 2 - 1]
5/12 + 1
MMC = 12
5/12/1 + 1/1/12
5/12 + 12/12
17/12
