4/3 - 8/5 as a fraction

Learn how to find what is 4/3 minus 8/5 in fraction form just in a few minutes. We have covered the easiest method to write 4/3 - 8/5 as a fraction and decimal.

Summary: 4/3 minus 8/5 = -4/15
Since both fractions have unequal denominators, 4/3 minus 8/5 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 4/3 and fraction 8/5 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 5. 15 is the LCM of 3 and 5. Multiplying the LCM 15 with the numerators and denominators of both fractions (4/3 x 15/15) - (8/5 x 15/15), and simplify further in order to have the common denominator. So the equivalent fraction for 4/3 is 20/15 and for 8/5 is 24/15. By simplifying this fraction subtraction 20/15 - 24/15, it becomes -4/15.

2. Cross multiplication method.

(4/3) - (8/5) using LCM Method:
What is 4/3 minus 8/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/3
Fraction B: 8/5

What to be found?
(4/3) - (8/5) = ?
Find what's the difference between 4/3 and 8/5.

step 2 Compare the denominators of fractions 4/3 and 8/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/3 and 8/5 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 4/3 and 8/5:
The LCM of 3 and 5 is 15.

step 4 Write the fractions 4/3 and 8/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/3 - 8/5
= [(4 x 15)/(3 x 15)] - [(8 x 15)/(5 x 15)]

step 5 Simplify the expression to have common denominator:
= 20/15 - 24/15

step 6 Take the common values out and rewrite the above expression like the below:
= 1/15 x (20/1 - 24/1)
= 1/15 x (20 - 24)

step 7Simplify the above expression further:
= 1/15 x -4
= -4/15
4/3 - 8/5 = -4/15

Hence,
4/3 minus 8/5 as a fraction is -4/15.
