Difference between Two Fractions with Different Denominators
The below solved example with step by step calculation shows how to find the difference between two fractions with different or unlike denominators by subtracting one from another.
Problem & Workout
Find what is the equivalent fraction by subtracting 3/4 from 5/6 (with unequal or different denominators).
step 1 Address formula and input values.
Input values:
5/6 & 3/4
5/6 + 3/4 = ?
step 2 For unequal denominators, find the LCM (least common multiple) for both denominators.
The LCM for 6 and 4 is 12.
step 3 To have common denominator, multiply LCM 12 with all numerators and denominators.
=(5 x 12)/(6 x 12)-(3 x 12)/(4 x 12)
=10/12-9/12
step 4 Find the difference between the numerators and rewrite it in a single form.
=(10 - 9)/12
=1/12
5/6-3/4=1/12
1/12 is the difference by subtracting 3/4 from 5/6.
Difference between Two Fractions with Same Denominators
Find what is the equivalent fraction by subtracting 3/7 from 5/7 (with same, equal or common denominators).
step 1 Address formula, and values.
Input values:
3/7 & 5/7
3/7 - 5/7 = ?
step 2 For same denominators, subtract the numerators directly and rewrite as below
= 3/7 - 5/7
= (3 - 5)/7
= -2/7
3/7 - 5/7 = -2/7
-2/7 is an equivalent fraction by subtracting 5/7 from 3/7.
Fractions Subtraction and Formula
Fraction Subtraction is a basic arithmetic operation used to find the difference between two or more fractions. It's a part of most important elementary school mathematics. For same or common denominator, the fraction subtraction is the difference between both numerators divided by the common denominator. For unlike, unequal or different denominators, the function LCM (least common multiple) is used to convert the fractions to have the common denominators to perform subtraction between the fractions.
