Find the LCM of denominators, 56 is the LCM of 7 and 8. Multiply the LCM 56 with all the numerators and denominators of both fractions (6/7 x 56/56) + (4/8 x 56/56) and simplify further in order to have the common denominators. By simplifying the fraction addition expression becomes 76/56.
The below workout with step by step calculation shows how to find the equivalent fraction between 6/7 and 4/8 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 6/7 plus 4/8 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
6/7+4/8 using LCM Method:
What is 6/7 plus 4/8 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 4/8
What to be found?
6/7+4/8 = ?
Find what's the sum of 6/7 and 4/8.
step 2 Compare the denominators of fractions 6/7 and 4/8 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 6/7 and 4/8 are not equal, it is said to be unlike fractions addition.
step 3For unlike fractions addition, find the LCM (least common multiple) of both denominators of fractions 6/7 and 4/8:
The LCM of 7 and 8 is 56.
step 4 Write the fractions 6/7 and 4/8 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=6/7+4/8
=(6 x 56)/(7 x 56)+(4 x 56)/(8 x 56)
step 5 Simplify the expression to have common denominator:
=48/56+28/56
step 6 Take the common values out and rewrite the above expression like the below:
=1/56 x (48/1+28/1)
=1/56 x (48 + 28)
step 7Simplify the above expression further:
=1/56 x 76
= 76/56
=19/14
6/7+4/8=19/14
Hence,
6/7 plus 4/8 equals to 19/14 in fraction.
6/7+4/8 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 4/8
What to be found?
6/7+4/8 = ?
Find what's the sum of 6/7 and 4/8.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (6 x 8), find the product of numerator of Fraction B and denominator of Fraction A (4 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 8) and rewrite the equation as like the below:
= (6 x 8) + (4 x 7)/(7 x 8)
step 3 Simplify and rewrite the fraction:
= (48 + 28)/56
= 76/56
= 19/14
6/7+4/8 = 19/14
Hence,
6/7 plus 4/8 = 19/14
