Answer 1

Resposta:

Explicação passo a passo:

X ÷ y =

15/99 ÷ 24/99

15/99 × 99/24

15/24 ==> ÷{3/3) = 5/8.

Y÷ x = 8/5 ✓

Answer 2

Explicação passo-a-passo:

0,1515...=x(10)

1,5151...=10x(10)

15,15...=100x

100x-x=15,15...-0,1515...

99x=15

x=15/99(÷3)

x=5/33

0,2424...=y(10)

2,4242...=10y(10)

24,24...=100y

100y-y=24,24...-0,2424...

99y=24

y=24/99(÷3)

y=8/33

y÷x

8/33÷5/33

8/33*33/5

264/165(÷33)

8/5
