Question

1 quintos - [2 terços -(2 sextos-1 doze avos)]+5 sextos

Answer 1

(2/6 - 1/12) = (24 - 6)/72 = 18/72 (÷18) = 1/4

(2/3 - 1/4) = (8-3)/12 = 5/12

(1/5-5/12) = (12-25)/60 = -13/60

(-13/60 + 5/6) = (-78 + 300)/360 = 222/360 (÷6) = 37/60

Answer 2

Resposta:

37/60

Explicação passo-a-passo:

1/5-[2/3-(2/6-1/12)]+5/6

1/5-[2/3-((4-1)/12)]+5/6

1/5-[2/3-(3/12)]+5/6

1/5-[2/3-3/12]+5/6

1/5-[(8-3)/12]+5/6

1/5-[5/12]+5/6

1/5-5/12+5/6

(12-25+50)/60

37/60
