Answer 1

Resposta:

Explicação passo a passo:

a)

3/2 + 3/6 * 7/4 - 2/5

3/2 + 21/24 - 2/5

(mmc entre 2, 5 e 24 = 120)

(180 + 105 - 48)/120

237/120 =

79/40

b) V9/4 : (1/2)^3 - 4/7

3/2 : 1/8 - 4/7

3/2 * 8 - 4/7

24/2 - 4/7

12 - 4/7

80/7

c) 6/8 [3/2 - 2/7 : (4/6+1/2)]

6/8 [3/2 - 2/7 : 7/6]

6/8 [3/2 - 2/7 * 6/7]

6/8 [3/2 - 12/49]

6/8 * 123/98

369/392
