PRECISO FAZER ISSO RAPIDAMENTTE :)

Answer 1

a) 4/3 x 3/8 = (4x3)/(3x8) = 12/24 = 1/2

b)  1/2 x 6/7 = (1x6)/(2x7) = 6/14 = 3/7

c) 6/15 x 5/3 = (6x5)/(15/3) = 30/45 = 2/3

d) 7/12 x 4/5 = (7x4)/(12x5) = 84/20 = 21/5

e) 1/8 x 16/9 x 6/5 = (1x16x6)/(8x9x5) = 96/360 = 4/15

f) 20/3 x 7/5 x 3/14 = (20x7x3)/(3x5x14) = 420/210 = 2
