8/5 - 1 as a fraction

Learn how to find what is 8/5 minus 1 in fraction form just in a few minutes. We have covered the easiest method to write 8/5 - 1 as a fraction and decimal.

Summary: 8/5 minus 1 = 3/5
Since both fractions have unequal denominators, 8/5 minus 1 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 8/5 and fraction 1 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 1. 5 is the LCM of 5 and 1. Multiplying the LCM 5 with the numerators and denominators of both fractions (8/5 x 5/5) - (1 x 5/5), and simplify further in order to have the common denominator. So the equivalent fraction for 8/5 is 8/5 and for 1 is 5/5. By simplifying this fraction subtraction 8/5 - 5/5, it becomes 3/5.

The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 1 from 8/5. use any one of the following methods to find the equivalent fraction for 8/5 minus 1.
1. LCM method
2. Cross multiplication method.

(8/5) - (1) using LCM Method:
What is 8/5 minus 1 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/5
Fraction B: 1/1

What to be found?
(8/5) - (1) = ?
Find what's the difference between 8/5 and 1.

step 2 Compare the denominators of fractions 8/5 and 1 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/5 and 1 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 1:
The LCM of 5 and 1 is 5.

step 4 Write the fractions 8/5 and 1 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/5 - 1
= [(8 x 5)/(5 x 5)] - [(1 x 5)/(1 x 5)]

step 5 Simplify the expression to have common denominator:
= 8/5 - 5/5

step 6 Take the common values out and rewrite the above expression like the below:
= 1/5 x (8/1 - 5/1)
= 1/5 x (8 - 5)

step 7Simplify the above expression further:
= 1/5 x 3
= 3/5
8/5 - 1 = 3/5

Hence,
8/5 minus 1 as a fraction is 3/5.

8/5 - 1 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/5
Fraction B: 1/1

What to be found?
(8/5)-(1) = ?
Find what's the difference between 8/5 and 1.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (8 x 1), find the product of numerator of Fraction B and denominator of Fraction A (1 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 1) and rewrite the equation as like the below:
= (8 x 1) - (1 x 5)/(5 x 1)

step 3 Simplify and rewrite the fraction:
= (8 - 5)/5
8/5 - 1 = 3/5

Hence,
8/5 minus 1 in fraction is 3/5
