Learn how to find what is 3/5 minus 3/7 in fraction form just in a few minutes. We have covered the easiest method to write 3/5 - 3/7 as a fraction and decimal.
Summary: 3/5 minus 3/7
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 3/5 and 3/7 having identical denominators before starting adding the fractions. Find the LCM of denominators, 35 is the LCM of 5 and 7. Multiply the LCM 35 with all the numerators and denominators of both fractions (3/5 x 35/35) - (3/7 x 35/35) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 6/35.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 3/7 from 3/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 3/5 minus 3/7.
1. LCM method
2. Cross multiplication method.
3/5-3/7 using LCM Method:
What is 3/5 minus 3/7 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 3/7
What to be found?
3/5-3/7 = ?
Find what's the difference between 3/5 and 3/7.
step 2 Compare the denominators of fractions 3/5 and 3/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/5 and 3/7 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 3/5 and 3/7:
The LCM of 5 and 7 is 35.
step 4 Write the fractions 3/5 and 3/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/5-3/7
=(3 x 35)/(5 x 35)-(3 x 35)/(7 x 35)
step 5 Simplify the expression to have common denominator:
=21/35-15/35
step 6 Take the common values out and rewrite the above expression like the below:
=1/35 x (21/1-15/1)
=1/35 x (21 - 15)
step 7Simplify the above expression further:
=1/35 x 6
=6/35
3/5-3/7=6/35
Hence,
3/5 minus 3/7 equals to 6/35 in fraction.
3/5-3/7 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 3/7
What to be found?
3/5-3/7 = ?
Find what's the difference between 3/5 and 3/7.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 7), 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 7) and rewrite the equation as like the below:
= (3 x 7) - (3 x 5)/(5 x 7)
step 3 Simplify and rewrite the fraction:
= (21 - 15)/35
3/5-3/7 = 6/35
Hence,
3/5 minus 3/7 = 6/35
