Learn how to find what is 7/2 minus 15/14 in fraction form just in a few minutes. We have covered the easiest method to write 7/2 - 15/14 as a fraction and decimal.
Summary: 7/2 minus 15/14 = 17/7
Since both fractions have unequal denominators, 7/2 minus 15/14 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 7/2 and fraction 15/14 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 14. 14 is the LCM of 2 and 14. Multiplying the LCM 14 with the numerators and denominators of both fractions (7/2 x 14/14) - (15/14 x 14/14), and simplify further in order to have the common denominator. So the equivalent fraction for 7/2 is 49/14 and for 15/14 is 15/14. By simplifying this fraction subtraction 49/14 - 15/14, it becomes 34/14.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 15/14 from 7/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/2 minus 15/14.
1. LCM method
2. Cross multiplication method.
(7/2) - (15/14) using LCM Method:
What is 7/2 minus 15/14 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 15/14
What to be found?
(7/2) - (15/14) = ?
Find what's the difference between 7/2 and 15/14.
step 2 Compare the denominators of fractions 7/2 and 15/14 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/2 and 15/14 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 7/2 and 15/14:
The LCM of 2 and 14 is 14.
step 4 Write the fractions 7/2 and 15/14 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/2 - 15/14
= [(7 x 14)/(2 x 14)] - [(15 x 14)/(14 x 14)]
step 5 Simplify the expression to have common denominator:
= 49/14 - 15/14
step 6 Take the common values out and rewrite the above expression like the below:
= 1/14 x (49/1 - 15/1)
= 1/14 x (49 - 15)
step 7Simplify the above expression further:
= 1/14 x 34
= 34/14
= 17/7
7/2 - 15/14 = 17/7
Hence,
7/2 minus 15/14 as a fraction is 17/7.
7/2 - 15/14 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/2
Fraction B: 15/14
What to be found?
(7/2)-(15/14) = ?
Find what's the difference between 7/2 and 15/14.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 14), find the product of numerator of Fraction B and denominator of Fraction A (15 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 14) and rewrite the equation as like the below:
= (7 x 14) - (15 x 2)/(2 x 14)
step 3 Simplify and rewrite the fraction:
= (98 - 30)/28
= 68/28
= 17/7
7/2 - 15/14 = 17/7
Hence,
7/2 minus 15/14 in fraction is 17/7
