Question

c)-2/3+5/6-1 frações me aguda por favor eu DoCoMo melhor resposta​

Answer 1

Resposta:

Explicação passo a passo:

= -2/3+5/6 - 1/1

Mmc (3,6)= 6

3,6: 2

3,3: 3

----------

1,1

= 2.3

= 6

= [2.(-2) + 1.5 - 6.1]/6

= [ - 4 + 5 - 6] / 6

= [ - 10 + 5]/6

= - 5/6

Answer 2

Resposta:

$\frac{-2}{3}+\frac{5}{6}-1\\\\\mathrm{Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{-a}{b}=-\frac{a}{b}\\\\\frac{-2}{3}=-\frac{2}{3}\\\\-\frac{2}{3}+\frac{5}{6}-1\\\\\mathrm{Converter\:para\:fracao}:\quad \:-1=\frac{-1}{1}\\\\-\frac{2}{3}+\frac{5}{6}+\frac{-1}{1}\\\\-\frac{4}{6}+\frac{5}{6}+\frac{-6}{6}\\\\\mathrm{Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}\\\\\frac{-4+5-6}{6}\\\\\mathrm{Somar:}\:-4+5-6=-5\\\\\frac{-5}{6}$$\mathrm{Aplicar\:as\:propriedades\:das\:fracoes}:\quad \frac{-a}{b}=-\frac{a}{b}\\\\-\frac{5}{6}$
