Question

Trabalho de Matemática

Answer 1

1) a) (3 - 4/5) . (5 - 2)

(8/5 - 4/5) . 3

(4/5) . 3 = 12/15 = 4/5

b) (1/2) - 1 + 1/16

1/2 - (17/16)

1/2 - 17/16 mmc = 16

8/16 - 17/16 = -9/16

a) (3 - 4/5) . (5 - 1/2)

(15/5 - 4/5) . (10/2 - 1/2)

(11/5) . (9/2)

99/10




(1/2) - 1 + 1/32

1/2 - (32/32 + 1/32)

1/2 - 33/32 mmc = 32

16/32 - 33/32 = -17/32
