2/8 - 1/10 as a fraction

Learn how to find what is 2/8 minus 1/10 in fraction form just in a few minutes. We have covered the easiest method to write 2/8 - 1/10 as a fraction and decimal.

Summary: 2/8 minus 1/10 = 3/20
Since both fractions have unequal denominators, 2/8 minus 1/10 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 2/8 and fraction 1/10 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 8 and 10. 40 is the LCM of 8 and 10. Multiplying the LCM 40 with the numerators and denominators of both fractions (2/8 x 40/40) - (1/10 x 40/40), and simplify further in order to have the common denominator. So the equivalent fraction for 2/8 is 10/40 and for 1/10 is 4/40. By simplifying this fraction subtraction 10/40 - 4/40, it becomes 6/40.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/10 from 2/8. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 2/8 minus 1/10.
1. LCM method
2. Cross multiplication method.

(2/8) - (1/10) using LCM Method:
What is 2/8 minus 1/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/8
Fraction B: 1/10

What to be found?
(2/8) - (1/10) = ?
Find what's the difference between 2/8 and 1/10.

step 2 Compare the denominators of fractions 2/8 and 1/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/8 and 1/10 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 2/8 and 1/10:
The LCM of 8 and 10 is 40.

step 4 Write the fractions 2/8 and 1/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/8 - 1/10
= [(2 x 40)/(8 x 40)] - [(1 x 40)/(10 x 40)]

step 5 Simplify the expression to have common denominator:
= 10/40 - 4/40

step 6 Take the common values out and rewrite the above expression like the below:
= 1/40 x (10/1 - 4/1)
= 1/40 x (10 - 4)

step 7Simplify the above expression further:
= 1/40 x 6
= 6/40
= 3/20
2/8 - 1/10 = 3/20

Hence,
2/8 minus 1/10 as a fraction is 3/20.

2/8 - 1/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/8
Fraction B: 1/10

What to be found?
(2/8)-(1/10) = ?
Find what's the difference between 2/8 and 1/10.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 10), find the product of numerator of Fraction B and denominator of Fraction A (1 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 10) and rewrite the equation as like the below:
= (2 x 10) - (1 x 8)/(8 x 10)

step 3 Simplify and rewrite the fraction:
= (20 - 8)/80
