Learn how to find what is 1/8 minus 1/13 in fraction form just in a few minutes. We have covered the easiest method to write 1/8 - 1/13 as a fraction and decimal.
Summary: 1/8 minus 1/13
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 1/8 and 1/13 having identical denominators before starting adding the fractions. Find the LCM of denominators, 104 is the LCM of 8 and 13. Multiply the LCM 104 with all the numerators and denominators of both fractions (1/8 x 104/104) - (1/13 x 104/104) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 5/104.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/13 from 1/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/8 minus 1/13.
1. LCM method
2. Cross multiplication method.
1/8-1/13 using LCM Method:
What is 1/8 minus 1/13 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 1/13
What to be found?
1/8-1/13 = ?
Find what's the difference between 1/8 and 1/13.
step 2 Compare the denominators of fractions 1/8 and 1/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/8 and 1/13 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 1/8 and 1/13:
The LCM of 8 and 13 is 104.
step 4 Write the fractions 1/8 and 1/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/8-1/13
=(1 x 104)/(8 x 104)-(1 x 104)/(13 x 104)
step 5 Simplify the expression to have common denominator:
=13/104-8/104
step 6 Take the common values out and rewrite the above expression like the below:
=1/104 x (13/1-8/1)
=1/104 x (13 - 8)
step 7Simplify the above expression further:
=1/104 x 5
=5/104
1/8-1/13=5/104
Hence,
1/8 minus 1/13 equals to 5/104 in fraction.
1/8-1/13 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/8
Fraction B: 1/13
What to be found?
1/8-1/13 = ?
Find what's the difference between 1/8 and 1/13.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 13), find the product of numerator of Fraction B and denominator of Fraction A (1 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 13) and rewrite the equation as like the below:
= (1 x 13) - (1 x 8)/(8 x 13)
step 3 Simplify and rewrite the fraction:
= (13 - 8)/104
1/8-1/13 = 5/104
Hence,
1/8 minus 1/13 = 5/104
