6 - 15/8 as a fraction

Learn how to find what is 6 minus 15/8 in fraction form just in a few minutes. We have covered the easiest method to write 6 - 15/8 as a fraction and decimal.

Summary: 6 minus 15/8 = 33/8
Since both fractions have unequal denominators, 6 minus 15/8 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 6 and fraction 15/8 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 8. 8 is the LCM of 1 and 8. Multiplying the LCM 8 with the numerators and denominators of both fractions (6 x 8/8) - (15/8 x 8/8), and simplify further in order to have the common denominator. So the equivalent fraction for 6 is 48/8 and for 15/8 is 15/8. By simplifying this fraction subtraction 48/8 - 15/8, it becomes 33/8.

(6) - (15/8) using LCM Method:
What is 6 minus 15/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/1
Fraction B: 15/8

What to be found?
(6) - (15/8) = ?
Find what's the difference between 6 and 15/8.

step 2 Compare the denominators of fractions 6 and 15/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 6 and 15/8 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 6 and 15/8:
The LCM of 1 and 8 is 8.

step 4 Write the fractions 6 and 15/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 6 - 15/8
= [(6 x 8)/(1 x 8)] - [(15 x 8)/(8 x 8)]

step 5 Simplify the expression to have common denominator:
= 48/8 - 15/8

step 6 Take the common values out and rewrite the above expression like the below:
= 1/8 x (48/1 - 15/1)
= 1/8 x (48 - 15)

step 7Simplify the above expression further:
= 1/8 x 33
= 33/8
6 - 15/8 = 33/8

Hence,
6 minus 15/8 as a fraction is 33/8.
