2) Given that 5b:8=2:5,find the value of b

3) Given that 2x/5 = 3y/8,find the ratio of x:y

4) Given that x: 3: 9/2 = 15/4 : 4 1/2 : y, find the value of x and y.

Answer 1

Step-by-step explanation:

here is the solution of your 3 parts but the fourth part I didn't understand

Answer 2

Answer:

1) a:400=6:25

so a/400=6/25

a=2400/25

A=95

2) 5b:8=2:5

so 5b/8=2/5

5b=16/5

b=16/25

b=0.64

3) 2x/5=3y/8

2x=15y/8

x/y=15/16

x:y=15:16
