Question

write these step by step?

1) 0.8y=0.2


2) 400w=80

Answer 1

Step-by-step explanation:

0.8y=0.2

y=0.2/0.8

y=1/4

y=0.25

400w=80

w=80/400

w=1/5

w=0.2

Answer 2

Step-by-step explanation:

$1)0.8y = 0.2 \\ y = \frac{0.2}{0.8} \\ y = \frac{0.1}{0.4} \\ \\ 2)400w = 80 \\ w= \frac{80}{400} \\w = \frac{2}{10}$
