Question

calcule as adições e subtração ​

Answer 1

Explicação passo-a-passo:

$g)\frac{10}{5} + \frac{3}{6} = 2 + \frac{1}{2} = mmc = 2$

$\frac{4 + 1}{2} = \frac{5}{2}$

$h) \frac{3}{2} + \frac{7}{3} = mmc = 6$

$\frac{9 + 14}{6} = \frac{23}{6}$

$i) \frac{9}{3} + \frac{1}{5} = 3 + \frac{1}{5} = mmc = 5$

$\frac{15 + 1}{5} = \frac{16}{5}$

$j) \frac{7}{4} + \frac{8}{9} = mmc = 36$

$\frac{56 + 32}{36} = \frac{88}{36} = \frac{44}{9}$
