Question

a) 11/6 - 1 - 1/5

b) (2/3 + 1/6) - ( 1 - 3/10)

Answer 1

Olá...

Explicação passo-a-passo:

a)

11/6 - 1 - 1/5  ⇒ mmc = 30

55 - 30 - 6/30

19/30

b)

(2/3 + 1/6) - ( 1 - 3/10)

(4 + 1/6) - (10 - 3/10)

5/6 - 7/10 ⇒ mmc = 30

25 - 21/30

4/30 ÷ 2

2/15

Bons estudos.

Answer 2

Resposta:

a) $\frac{19}{30}$

b) $\frac{4}{30}$

Explicação passo-a-passo:

a)$\frac{11}{6}$-1-$\frac{1}{5}$=

$\frac{55}{30}$-$\frac{30}{30}$-$\frac{6}{30}$=

$\frac{55-30-6}{30}$=

$\frac{25-6}{30}$=

$\frac{19}{30}$

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

($\frac{4}{6}$+$\frac{1}{6}$)-($\frac{10}{10}$-$\frac{3}{10}$)=

($\frac{4+1}{6}$)-($\frac{10-3}{10}$)=

$\frac{5}{6}$-$\frac{7}{10}$=

$\frac{25}{30}$-$\frac{21}{30}$=

$\frac{25-21}{30}$=

$\frac{4}{30}$
