Question

Third Proportion of 5.25 and 7

Answer 1

Let the required third proportion be x

therefore, 5•25, 7, x are in continued proportion

= 5•25 : 7 = 7 : x

= 5x = 7*7

= x= 7*7/ 5•25

= x = 49/5•25 = 28/3

= x = 9⅓

therefore, Required proportion is 9⅓

5x=7*7

x=7*7\5.25

x=49/5.25=28/3

x=9⅓
