step 1Find the product of Means
5 x 22 = 110
step 2If 2 ratios are in proportion, the product of Extremes and product of Means should be equal
Product of Extremes = Product of Means
Product of Extremes = 5 x 22
Product of Extremes = 110
step 3To find the Extremes, find the factors of 110
Factors of 110 = 2, 10, 55, 11
step 4Write the possible pair of multiplication factors (Extremes) that makes 110
2 x 55 = 110
10 x 11 = 110
Either 2 & 55 or 10 & 11 are the the Extremes of this proportion
step 5Apply the Extreme values in the proportion statement
Product of Extremes = Product of Means
2 x 55 = 5 x 22
or
10 x 11 = 5 x 22
or
step 7Write the above fractions in the ratio form
2:5 = 22:55
or
10:5 = 22:11
step 8Therefore, the two proportions are
2:5 :: 22:55 & 10:5 :: 22:11
