Using 8 and 13 as means, write any two proportions.

2:8 :: 13:52 and 4:8 :: 13:26

step 1

Find the product of Means

8 x 13 = 104

8 x 13 = 104

step 2

If 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 = 8 x 13

Product of Extremes = 104

Product of Extremes = Product of Means

Product of Extremes = 8 x 13

step 4

Write the possible pair of multiplication factors (Extremes) that makes 104

2 x 52 = 104

4 x 26 = 104

Either 2 & 52 or 4 & 26 are the the Extremes of this proportion

2 x 52 = 104

4 x 26 = 104

Either 2 & 52 or 4 & 26 are the the Extremes of this proportion

step 5

Apply the Extreme values in the proportion statement

Product of Extremes = Product of Means

2 x 52 = 8 x 13

or

4 x 26 = 8 x 13

or

Product of Extremes = Product of Means

2 x 52 = 8 x 13

or

4 x 26 = 8 x 13

or

step 6

Write the above expression in the fraction form
