How to Find the Average of Two Fractions?
User may refer the below example workout with step by step calculation to find average between two fractional numbers.
Example Problem & Workout
Find the average of 1/7 and 1/6.
step 1 Address formula, input parameters & values.
Input parameters & values:
1/7 & 1/6
step 2 Find the sum of 1/7 & 1/6 by using LCM (least common multiple) method for fractions with unlike or different denominators.
= 1/7 + 1/6
LCM for denominators 7 & 6 is 42
Multiply LCM 42 with all the numerators & denominators of each fractions
= (1 x 42)/(7 x 42) + (1 x 42)/(6 x 42)
Simplify the expression to have the common denominator
= 6/42 = 7/42
= (6 + 7)/42
Rewrite the above expression as below
1/7 + 1/6 = 13/42
step 3 Divide the sum by total count of fractions
= (13/42) / 2
= 13/(42 x 2)
(1/7 + 1/6)/2 = 13/84
Thus, 13/84 is the average of 1/7 and 1/6.
Fractions Average & Formula
Fractions Average is one of a basic arithmetic operations used in mathematics to find the mean, central value or average between two or more fractions. It can be found by finding the sum of fractions which are having same or different denominators, divided by the total count of fractions. LCM (least common multiple) or LCD (least common denominator) method is used to find the sum of fractions with unlike or different denominators.
