Answer 2

Resposta:

a) 1/2

b) 4/15

c) 1/12

d) 4/9

Explicação passo a passo:

a) mmc = 22

$\frac{15-4}{22} \\\\= \frac{11}{22} (simplificando por 11)\\\\= \frac{1}{2}$

b) mmc = 15

$\frac{9-5}{15}\\\\= \frac{4}{15}$

c) mmc = 12

$\frac{9-8}{12}\\\\= \frac{1}{12}$

d) mmc = 9

$\frac{7-3}{9} \\\\=\frac{4}{9}$
