Learn how to find what is 8/5 minus 2/10 in fraction form just in a few minutes. We have covered the easiest method to write 8/5 - 2/10 as a fraction and decimal.
Summary: 8/5 minus 2/10
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 8/5 and 2/10 having identical denominators before starting adding the fractions. Find the LCM of denominators, 10 is the LCM of 5 and 10. Multiply the LCM 10 with all the numerators and denominators of both fractions (8/5 x 10/10) - (2/10 x 10/10) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 14/10.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/10 from 8/5. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 8/5 minus 2/10.
1. LCM method
2. Cross multiplication method.
8/5-2/10 using LCM Method:
What is 8/5 minus 2/10 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/5
Fraction B: 2/10
What to be found?
8/5-2/10 = ?
Find what's the difference between 8/5 and 2/10.
step 2 Compare the denominators of fractions 8/5 and 2/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/5 and 2/10 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 8/5 and 2/10:
The LCM of 5 and 10 is 10.
step 4 Write the fractions 8/5 and 2/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=8/5-2/10
=(8 x 10)/(5 x 10)-(2 x 10)/(10 x 10)
step 5 Simplify the expression to have common denominator:
=16/10-2/10
step 6 Take the common values out and rewrite the above expression like the below:
=1/10 x (16/1-2/1)
=1/10 x (16 - 2)
step 7Simplify the above expression further:
=1/10 x 14
= 14/10
=7/5
8/5-2/10=7/5
Hence,
8/5 minus 2/10 equals to 7/5 in fraction.
8/5-2/10 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/5
Fraction B: 2/10
What to be found?
8/5-2/10 = ?
Find what's the difference between 8/5 and 2/10.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (8 x 10), 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 10) and rewrite the equation as like the below:
= (8 x 10) - (2 x 5)/(5 x 10)
step 3 Simplify and rewrite the fraction:
= (80 - 10)/50
= 70/50
= 7/5
8/5-2/10 = 7/5
Hence,
8/5 minus 2/10 = 7/5
