Me ajudem plmds a fazer essas expressões​

Answer 1

Resposta:

Explicação passo-a-passo:

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

3/2 * 1/3 = 3/6

5/6 + 3/6 = 8/6 = 4/3

5 + 3/4 * 4/6 =

3/4 * 4/6 = 12/24 = 1/2

5 + 1/2 = 11/2 ou 5,5

(5 + 3/4) * 4/6 =

23/4 * 4/6 = 92/24 = 23/6 ou 3,8333...

5 + 3/4 - 4/6 : 2/3 =

23/4 - 4/6 * 3/2 =

23/4 - 12/12 = 23/4 - 1 = 19/4 ou 4,75

(1/4 - 1/6) + (2/3 + 1/5) =

((3-2)/12) + ((10+3)/15)

1/2 + 13/15 = 41/30 ou 1,3666...

20/3 * (6 - 5/4 + 1/5) =

20/3 * 99/20 = 1980/60 = 33

(4 - 1/2) / (7/4 - 5/6 + 31/2 : 6) =

7/2 / (11/12 + 31/12) =

7/2 : 7/2 = 7/2 * 2/7 = 14/14 = 1

(1/2 + 1/3) * 6/5

5/6 * 6/5 = 30/30 = 1
