Question

• Fill in the missing numbers in the following equivalent ratios: (a) 15/18=?/6=10/?=?/30

Answer 1

Let us rewrite the question as

15/18 = x/6 = 10/y = z/30

15/18 = x/6
x = (15*6)/18
x = 5

15/18 = 10/y
15*y = 18*10
y = 180/15
y = 12

15/18 = z/30
z = (15*30)/18
z = 25

So,
15/18 = 5/6 = 10/12 = 25/30
