Como calcular:a) 5/3+7/3-16/3 b) 1/2+2/3-1/8 c)5/3+17/7+11/5

Answer 1

Olá, boa noite ☺

Resoluções:

a)

$\\ \frac{5}{3} + \frac{7}{3} - \frac{16}{3} \\ \\\ \frac{(5+7-16)}{3}= \boxed{ \boxed{- \frac{4}{3} }}$

b)

$\\ \frac{1}{2} + \frac{2}{3} - \frac{1}{8}$

m.m.c.(1,3,8)=24

$\frac{(12+16-3)}{24} = \boxed{ \boxed{ \frac{25}{24}} }$

c)

$\\ \frac{5}{3} + \frac{17}{7}+ \frac{11}{5}$

m.m.c.(3,5,7)=105

$\frac{(175+255+231)}{105} =\boxed{ \boxed{ \frac{661}{105} }}$

Bons estudos :)
