Explicação passo-a-passo:

2)

a) 2/9 × 1.800

1800÷ 9 = 200

2/200 = 1/100 = 0,01

b) 15/13 × 52/3 × 6/45

15/45 × 52/13 × 6/3

1/3 × 4 × 2 = 8/3

c) 1 2/7 × 21/100

1 + 2/7 × 21/100

(7 + 2)/7 × 21/100

9/7 × 21/100

9 × 3/100 = 27/100 = 0,27

d) 6/11 × 55/24 × 1/5

6/24 × 55/5 × 1/11

1/4 × 11 × 1/11 = 1/4

e) 1/28 × 4/3 × 9/2

1/28 × 4/2 × 9/3

1/28 × 2 × 3

6/28 = 3/14

f) 1 1/8 × 4/15 × 6/20

(1 + 1/8) × 4/15 × 3/10

(8 + 1)/8 × 4/10 × 3/15

9/8 × 2/5 × 1/5

9/5 × 2/8 × 1/5

9/5 × 1/5 × 1/4 = 9/(5.5.4) = 9/100
