What fraction must be subtracted from the sum of 1/4 and 1/6 to have an average of 1/12 of all the two fractions

so 1/3 must be subtracted from the sum of 1/4 and 1/6 to have an average of 1/12 of all the two fractions.

Step-by-step explanation:

let the fraction be x

(1/4 + 1/6)-x =  1/12

or, 10/24 - x = 1/12

or, 5/12-1/12 = x

so, x = 4/12 = 1/3

47 - 90 = 43

43 - 180 = x

x = 137
