7/2 - 12/5 as a fraction

Learn how to find what is 7/2 minus 12/5 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 12/5 as a fraction and decimal.

Summary: 7/2 minus 12/5 = 11/10
Since both fractions have unequal denominators, 7/2 minus 12/5 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/2 and fraction 12/5 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 5. 10 is the LCM of 2 and 5. Multiplying the LCM 10 with the numerators and denominators of both fractions (7/2 x 10/10) - (12/5 x 10/10), and simplify further in order to have the common denominator. So the equivalent fraction for 7/2 is 35/10 and for 12/5 is 24/10. By simplifying this fraction subtraction 35/10 - 24/10, it becomes 11/10.

2. Cross multiplication method.

(7/2) - (12/5) using LCM Method:
What is 7/2 minus 12/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 12/5

What to be found?
(7/2) - (12/5) = ?
Find what's the difference between 7/2 and 12/5.

step 2 Compare the denominators of fractions 7/2 and 12/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/2 and 12/5 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 7/2 and 12/5:
The LCM of 2 and 5 is 10.

step 4 Write the fractions 7/2 and 12/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 - 12/5
= [(7 x 10)/(2 x 10)] - [(12 x 10)/(5 x 10)]

step 5 Simplify the expression to have common denominator:
= 35/10 - 24/10

step 6 Take the common values out and rewrite the above expression like the below:
= 1/10 x (35/1 - 24/1)
= 1/10 x (35 - 24)

step 7Simplify the above expression further:
= 1/10 x 11
= 11/10
7/2 - 12/5 = 11/10

Hence,
7/2 minus 12/5 as a fraction is 11/10.
