Question

URGENTEEEEE!!!!!!!!
A) 3/4+7/10
b) 8/15+1/30
c) 5/14+3/29

Answer 1

Explicação passo-a-passo:

$a) \frac{3}{4} + \frac{7}{10} = mmc = 20$

$\frac{15 + 14}{20} = \frac{29}{20}$

$b) \frac{8}{15} + \frac{1}{30} = mmc = 30$

$\frac{16 + 1}{30} = \frac{17}{30}$

$c) \frac{5}{14} + \frac{3}{29} = mmc = 406$

$\frac{145 + 42}{406} = \frac{167}{406}$
