Answer 1

Answer:

a= 6

b= 6

c=1/4

d= 8/7

Step-by-step explanation:

a. 5/9 × x/10 = 30/90

x/18= 1/3

x= 1/3×18

x= 6

b. x/ 5 × 7/6= 42/30

7x/30= 7/5

7x= 7/5× 30

7x= 42

x= 6

c. (x/y) × 5/2= 15/24

x/y = 15/24÷ 5/2

x/y= 15/24× 2/5

x/y = 1/4

x= 1

y= 4

d.3/7× y/x= 24/49

y/x= 24/49÷ 3/7

y/x= 24/49 × 7/3

y/x= 8/7

y= 8

x= 7
