Learn how to find what is 3/5 minus 4/8 in fraction form just in a few minutes. We have covered the easiest method to write 3/5 - 4/8 as a fraction and decimal.
Summary: 3/5 minus 4/8
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 3/5 and 4/8 having identical denominators before starting adding the fractions. Find the LCM of denominators, 40 is the LCM of 5 and 8. Multiply the LCM 40 with all the numerators and denominators of both fractions (3/5 x 40/40) - (4/8 x 40/40) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 4/40.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 4/8 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 4/8.
1. LCM method
2. Cross multiplication method.
3/5-4/8 using LCM Method:
What is 3/5 minus 4/8 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 4/8
What to be found?
3/5-4/8 = ?
Find what's the difference between 3/5 and 4/8.
step 2 Compare the denominators of fractions 3/5 and 4/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/5 and 4/8 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 4/8:
The LCM of 5 and 8 is 40.
step 4 Write the fractions 3/5 and 4/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/5-4/8
=(3 x 40)/(5 x 40)-(4 x 40)/(8 x 40)
step 5 Simplify the expression to have common denominator:
=24/40-20/40
step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (24/1-20/1)
=1/40 x (24 - 20)
step 7Simplify the above expression further:
=1/40 x 4
= 4/40
=1/10
3/5-4/8=1/10
Hence,
3/5 minus 4/8 equals to 1/10 in fraction.
3/5-4/8 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/5
Fraction B: 4/8
What to be found?
3/5-4/8 = ?
Find what's the difference between 3/5 and 4/8.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 8), find the product of numerator of Fraction B and denominator of Fraction A (4 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 8) and rewrite the equation as like the below:
= (3 x 8) - (4 x 5)/(5 x 8)
step 3 Simplify and rewrite the fraction:
= (24 - 20)/40
= 4/40
= 1/10
3/5-4/8 = 1/10
Hence,
3/5 minus 4/8 = 1/10
