1/3 - 4/13 as a fraction

Learn how to find what is 1/3 minus 4/13 in fraction form just in a few minutes. We have covered the easiest method to write 1/3 - 4/13 as a fraction and decimal.

Summary: 1/3 minus 4/13 = 1/39
Since both fractions have unequal denominators, 1/3 minus 4/13 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/3 and fraction 4/13 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 3 and 13. 39 is the LCM of 3 and 13. Multiplying the LCM 39 with the numerators and denominators of both fractions (1/3 x 39/39) - (4/13 x 39/39), and simplify further in order to have the common denominator. So the equivalent fraction for 1/3 is 13/39 and for 4/13 is 12/39. By simplifying this fraction subtraction 13/39 - 12/39, it becomes 1/39.

2. Cross multiplication method.

(1/3) - (4/13) using LCM Method:
What is 1/3 minus 4/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/3
Fraction B: 4/13

What to be found?
(1/3) - (4/13) = ?
Find what's the difference between 1/3 and 4/13.

step 2 Compare the denominators of fractions 1/3 and 4/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/3 and 4/13 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 1/3 and 4/13:
The LCM of 3 and 13 is 39.

step 4 Write the fractions 1/3 and 4/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/3 - 4/13
= [(1 x 39)/(3 x 39)] - [(4 x 39)/(13 x 39)]

step 5 Simplify the expression to have common denominator:
= 13/39 - 12/39

step 6 Take the common values out and rewrite the above expression like the below:
= 1/39 x (13/1 - 12/1)
= 1/39 x (13 - 12)

step 7Simplify the above expression further:
= 1/39 x 1
= 1/39
1/3 - 4/13 = 1/39

Hence,
1/3 minus 4/13 as a fraction is 1/39.
