Learn how to find what is 15/8 minus 5/13 in fraction form just in a few minutes. We have covered the easiest method to write 15/8 - 5/13 as a fraction and decimal.
Summary: 15/8 minus 5/13 = 155/104
Since both fractions have unequal denominators, 15/8 minus 5/13 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 15/8 and fraction 5/13 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 8 and 13. 104 is the LCM of 8 and 13. Multiplying the LCM 104 with the numerators and denominators of both fractions (15/8 x 104/104) - (5/13 x 104/104), and simplify further in order to have the common denominator. So the equivalent fraction for 15/8 is 195/104 and for 5/13 is 40/104. By simplifying this fraction subtraction 195/104 - 40/104, it becomes 155/104.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 5/13 from 15/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 15/8 minus 5/13.
1. LCM method
2. Cross multiplication method.
(15/8) - (5/13) using LCM Method:
What is 15/8 minus 5/13 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/8
Fraction B: 5/13
What to be found?
(15/8) - (5/13) = ?
Find what's the difference between 15/8 and 5/13.
step 2 Compare the denominators of fractions 15/8 and 5/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 15/8 and 5/13 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 15/8 and 5/13:
The LCM of 8 and 13 is 104.
step 4 Write the fractions 15/8 and 5/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 15/8 - 5/13
= [(15 x 104)/(8 x 104)] - [(5 x 104)/(13 x 104)]
step 5 Simplify the expression to have common denominator:
= 195/104 - 40/104
step 6 Take the common values out and rewrite the above expression like the below:
= 1/104 x (195/1 - 40/1)
= 1/104 x (195 - 40)
step 7Simplify the above expression further:
= 1/104 x 155
= 155/104
15/8 - 5/13 = 155/104
Hence,
15/8 minus 5/13 as a fraction is 155/104.
15/8 - 5/13 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 15/8
Fraction B: 5/13
What to be found?
(15/8)-(5/13) = ?
Find what's the difference between 15/8 and 5/13.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (15 x 13), find the product of numerator of Fraction B and denominator of Fraction A (5 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:
= (15 x 13) - (5 x 8)/(8 x 13)
step 3 Simplify and rewrite the fraction:
= (195 - 40)/104
15/8 - 5/13 = 155/104
Hence,
15/8 minus 5/13 in fraction is 155/104
