Learn how to find what is 7/5 minus 2/4 in fraction form just in a few minutes. We have covered the easiest method to write 7/5 - 2/4 as a fraction and decimal.
Summary: 7/5 minus 2/4
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 7/5 and 2/4 having identical denominators before starting adding the fractions. Find the LCM of denominators, 20 is the LCM of 5 and 4. Multiply the LCM 20 with all the numerators and denominators of both fractions (7/5 x 20/20) - (2/4 x 20/20) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 18/20.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/4 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 2/4.
1. LCM method
2. Cross multiplication method.
7/5-2/4 using LCM Method:
What is 7/5 minus 2/4 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 2/4
What to be found?
7/5-2/4 = ?
Find what's the difference between 7/5 and 2/4.
step 2 Compare the denominators of fractions 7/5 and 2/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/5 and 2/4 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 2/4:
The LCM of 5 and 4 is 20.
step 4 Write the fractions 7/5 and 2/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=7/5-2/4
=(7 x 20)/(5 x 20)-(2 x 20)/(4 x 20)
step 5 Simplify the expression to have common denominator:
=28/20-10/20
step 6 Take the common values out and rewrite the above expression like the below:
=1/20 x (28/1-10/1)
=1/20 x (28 - 10)
step 7Simplify the above expression further:
=1/20 x 18
= 18/20
=9/10
7/5-2/4=9/10
Hence,
7/5 minus 2/4 equals to 9/10 in fraction.
7/5-2/4 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/5
Fraction B: 2/4
What to be found?
7/5-2/4 = ?
Find what's the difference between 7/5 and 2/4.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (7 x 4), find the product of numerator of Fraction B and denominator of Fraction A (2 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 4) and rewrite the equation as like the below:
= (7 x 4) - (2 x 5)/(5 x 4)
step 3 Simplify and rewrite the fraction:
= (28 - 10)/20
= 18/20
= 9/10
7/5-2/4 = 9/10
Hence,
7/5 minus 2/4 = 9/10
