Help pls !! Uh grade 5 work aka Primary 5 in my country

The squares have same area thus if we suppose that the area of one of them is A the other one has a area of A .

The shaded area is 20/100 × A thus the unshaded area is ( 80/100 × A )+ ( 80/100 × A ) , So the unshaded area is 160/100 × A .

Thus the ratio of the shaded area of the figure to unshaded area of the figure is :

( 20A / 100 ) ÷ ( 160A / 100 ) =

A / 100 s are simplify

20 ÷ 160 =

2 ÷ 16 =

1/8

Step-by-step explanation:

1/8
