Question

A) 3 1/2 + 5 2/3 - 1/2 B) 2 1/2 + 3/2 x 1/2 Resolvam essas expressões por favor

Answer 1

$3 \times \frac{1}{2} + 5 \times \frac{2}{3} - \frac{1}{2}$

$= \frac{3}{2} + \frac{10}{3} - \frac{1}{2}$

Após isso, faremos o MMC

2*3=6

$\frac{(3 \times 2 ) + (10 \times 2) - (1 \times 3)}{6}$

$\frac{6 + 20 - 3}{6} = \frac{26 - 3}{6} = \frac{23}{6}$

Dessa forma a resposta será 23/6
