Question

Shade the grid to represent the ratio. Then find the missing number.

11/20 = __/100

Answer 1

Answer: The missing number is 55

The denominators are 20 and 100. We multiply by 5 to jump from the smaller denominator to the larger.

Do the same for the numerators

11*5 = 55

Or you can solve the proportion below for x

11/20 = x/100

11*100 = 20*x

1100 = 20x

20x = 1100

x = 1100/20

x = 55
