By simplifying the fraction addition expression becomes 133/90.
The below workout with step by step calculation shows how to find the equivalent fraction between 7/9 and 7/10 by adding two fractions with different, unequal or unlike denominators. The sum in fraction form for 7/9 plus 7/10 can be obtained by using anyone of the two methods below.
1. LCM method
2. Cross multiplication method.
7/9+7/10 using LCM Method:
What is 7/9 plus 7/10 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/9
Fraction B: 7/10
What to be found?
7/9+7/10 = ?
Find what's the sum of 7/9 and 7/10.
step 2 Compare the denominators of fractions 7/9 and 7/10 to identify whether it is a like or unlike fraction addition. Since the denominators of given fractions 7/9 and 7/10 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 7/9 and 7/10:
The LCM of 9 and 10 is 90.
step 4 Write the fractions 7/9 and 7/10 in the addition expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/9+7/10
=(7 x 90)/(9 x 90)+(7 x 90)/(10 x 90)
step 5 Simplify the expression to have common denominator:
=70/90+63/90
step 6 Take the common values out and rewrite the above expression like the below:
=1/90 x (70/1+63/1)
=1/90 x (70 + 63)
step 7Simplify the above expression further:
=1/90 x 133
=133/90
7/9+7/10=133/90
Hence,
