Learn how to find what is 7/5 minus 3/12 in fraction form just in a few minutes. We have covered the easiest method to write 7/5 - 3/12 as a fraction and decimal.
Summary: 7/5 minus 3/12
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 7/5 and 3/12 having identical denominators before starting adding the fractions. Find the LCM of denominators, 60 is the LCM of 5 and 12. Multiply the LCM 60 with all the numerators and denominators of both fractions (7/5 x 60/60) - (3/12 x 60/60) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 69/60.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/12 from 7/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 7/5 minus 3/12.
1. LCM method
2. Cross multiplication method.
7/5-3/12 using LCM Method:
What is 7/5 minus 3/12 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 3/12
What to be found?
7/5-3/12 = ?
Find what's the difference between 7/5 and 3/12.
step 2 Compare the denominators of fractions 7/5 and 3/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/5 and 3/12 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 7/5 and 3/12:
The LCM of 5 and 12 is 60.
step 4 Write the fractions 7/5 and 3/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/5-3/12
=(7 x 60)/(5 x 60)-(3 x 60)/(12 x 60)
step 5 Simplify the expression to have common denominator:
=84/60-15/60
step 6 Take the common values out and rewrite the above expression like the below:
=1/60 x (84/1-15/1)
=1/60 x (84 - 15)
step 7Simplify the above expression further:
=1/60 x 69
= 69/60
=23/20
7/5-3/12=23/20
Hence,
7/5 minus 3/12 equals to 23/20 in fraction.
7/5-3/12 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 3/12
What to be found?
7/5-3/12 = ?
Find what's the difference between 7/5 and 3/12.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 12), find the product of numerator of Fraction B and denominator of Fraction A (3 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 12) and rewrite the equation as like the below:
= (7 x 12) - (3 x 5)/(5 x 12)
step 3 Simplify and rewrite the fraction:
= (84 - 15)/60
= 69/60
= 23/20
7/5-3/12 = 23/20
Hence,
7/5 minus 3/12 = 23/20
