Learn how to find what is 8/7 minus 1/15 in fraction form just in a few minutes. We have covered the easiest method to write 8/7 - 1/15 as a fraction and decimal.
Summary: 8/7 minus 1/15 = 113/105
Since both fractions have unequal denominators, 8/7 minus 1/15 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 8/7 and fraction 1/15 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 7 and 15. 105 is the LCM of 7 and 15. Multiplying the LCM 105 with the numerators and denominators of both fractions (8/7 x 105/105) - (1/15 x 105/105), and simplify further in order to have the common denominator. So the equivalent fraction for 8/7 is 120/105 and for 1/15 is 7/105. By simplifying this fraction subtraction 120/105 - 7/105, it becomes 113/105.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/15 from 8/7. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 8/7 minus 1/15.
1. LCM method
2. Cross multiplication method.
(8/7) - (1/15) using LCM Method:
What is 8/7 minus 1/15 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/7
Fraction B: 1/15
What to be found?
(8/7) - (1/15) = ?
Find what's the difference between 8/7 and 1/15.
step 2 Compare the denominators of fractions 8/7 and 1/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/7 and 1/15 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 8/7 and 1/15:
The LCM of 7 and 15 is 105.
step 4 Write the fractions 8/7 and 1/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/7 - 1/15
= [(8 x 105)/(7 x 105)] - [(1 x 105)/(15 x 105)]
step 5 Simplify the expression to have common denominator:
= 120/105 - 7/105
step 6 Take the common values out and rewrite the above expression like the below:
= 1/105 x (120/1 - 7/1)
= 1/105 x (120 - 7)
step 7Simplify the above expression further:
= 1/105 x 113
= 113/105
8/7 - 1/15 = 113/105
Hence,
8/7 minus 1/15 as a fraction is 113/105.
8/7 - 1/15 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/7
Fraction B: 1/15
What to be found?
(8/7)-(1/15) = ?
Find what's the difference between 8/7 and 1/15.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (8 x 15), find the product of numerator of Fraction B and denominator of Fraction A (1 x 7), and find the product of both denominators of Fraction A and Fraction B (7 x 15) and rewrite the equation as like the below:
= (8 x 15) - (1 x 7)/(7 x 15)
step 3 Simplify and rewrite the fraction:
= (120 - 7)/105
8/7 - 1/15 = 113/105
Hence,
8/7 minus 1/15 in fraction is 113/105
