Summary: 9/7 minus 8/10
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 9/7 and 8/10 having identical denominators before starting adding the fractions. Find the LCM of denominators, 70 is the LCM of 7 and 10. Multiply the LCM 70 with all the numerators and denominators of both fractions (9/7 x 70/70) - (8/10 x 70/70) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 34/70.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 8/10 from 9/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 9/7 minus 8/10.
1. LCM method
2. Cross multiplication method.
9/7-8/10 using LCM Method:
What is 9/7 minus 8/10 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 8/10
What to be found?
9/7-8/10 = ?
Find what's the difference between 9/7 and 8/10.
step 2 Compare the denominators of fractions 9/7 and 8/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/7 and 8/10 are not equal, it is said to be unlike fractions subtraction.
step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 9/7 and 8/10:
The LCM of 7 and 10 is 70.
step 4 Write the fractions 9/7 and 8/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=9/7-8/10
=(9 x 70)/(7 x 70)-(8 x 70)/(10 x 70)
step 5 Simplify the expression to have common denominator:
=90/70-56/70
step 6 Take the common values out and rewrite the above expression like the below:
=1/70 x (90/1-56/1)
=1/70 x (90 - 56)
step 7Simplify the above expression further:
=1/70 x 34
= 34/70
=17/35
9/7-8/10=17/35
Hence,
9/7 minus 8/10 equals to 17/35 in fraction.
9/7-8/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 8/10
What to be found?
9/7-8/10 = ?
Find what's the difference between 9/7 and 8/10.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (9 x 10), find the product of numerator of Fraction B and denominator of Fraction A (8 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 10) and rewrite the equation as like the below:
= (9 x 10) - (8 x 7)/(7 x 10)
step 3 Simplify and rewrite the fraction:
= (90 - 56)/70
= 34/70
= 17/35
9/7-8/10 = 17/35
Hence,
9/7 minus 8/10 = 17/35
