3/4 - 7/10 as a fraction

Learn how to find what is 3/4 minus 7/10 in fraction form just in a few minutes. We have covered the easiest method to write 3/4 - 7/10 as a fraction and decimal.

Summary: 3/4 minus 7/10 = 1/20
Since both fractions have unequal denominators, 3/4 minus 7/10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 3/4 and fraction 7/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 10. 20 is the LCM of 4 and 10. Multiplying the LCM 20 with the numerators and denominators of both fractions (3/4 x 20/20) - (7/10 x 20/20), and simplify further in order to have the common denominator. So the equivalent fraction for 3/4 is 15/20 and for 7/10 is 14/20. By simplifying this fraction subtraction 15/20 - 14/20, it becomes 1/20.

2. Cross multiplication method.

(3/4) - (7/10) using LCM Method:
What is 3/4 minus 7/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 7/10

What to be found?
(3/4) - (7/10) = ?
Find what's the difference between 3/4 and 7/10.

step 2 Compare the denominators of fractions 3/4 and 7/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/4 and 7/10 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 3/4 and 7/10:
The LCM of 4 and 10 is 20.

step 4 Write the fractions 3/4 and 7/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 3/4 - 7/10
= [(3 x 20)/(4 x 20)] - [(7 x 20)/(10 x 20)]

step 5 Simplify the expression to have common denominator:
= 15/20 - 14/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (15/1 - 14/1)
= 1/20 x (15 - 14)

step 7Simplify the above expression further:
= 1/20 x 1
= 1/20
3/4 - 7/10 = 1/20

Hence,
3/4 minus 7/10 as a fraction is 1/20.
