4/5 - 3 as a fraction

Learn how to find what is 4/5 minus 3 in fraction form just in a few minutes. We have covered the easiest method to write 4/5 - 3 as a fraction and decimal.

Summary: 4/5 minus 3 = -11/5
Since both fractions have unequal denominators, 4/5 minus 3 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 4/5 and fraction 3 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 (4/5 x 5/5) - (3 x 5/5), and simplify further in order to have the common denominator. So the equivalent fraction for 4/5 is 4/5 and for 3 is 15/5. By simplifying this fraction subtraction 4/5 - 15/5, it becomes -11/5.

CALCULATION: 4/5 - 3 as a fraction
4/5 - 3 = (?)
4/5 - 3/1 = [(4 x 1) - (3 x 5)]/(5 x 1)
= (4 - 15)/5
= -11/5
4/5 - 3 = -11/5
4/5 minus 3 as a fraction is -11/5.

where
4/5 is a proper fraction as a minuend,
3 is a whole number as a subtrahend,
-11/5 is the difference between 4/5 and 3.

The below workout with step by step calculation shows how to find the difference between fraction and a whole number by subtracting 3 from 4/5. use any one of the following methods to find the equivalent fraction for 4/5 minus 3.
1. LCM method
2. Cross multiplication method.

(4/5) - (3) using LCM Method:
What is 4/5 minus 3 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/5
Fraction B: 3/1

What to be found?
(4/5) - (3) = ?
Find what's the difference between 4/5 and 3.

step 2 Compare the denominators of fractions 4/5 and 3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 4/5 and 3 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 4/5 and 3:
The LCM of 5 and 1 is 5.

step 4 Write the fractions 4/5 and 3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 4/5 - 3
= [(4 x 5)/(5 x 5)] - [(3 x 5)/(1 x 5)]

step 5 Simplify the expression to have common denominator:
= 4/5 - 15/5

step 6 Take the common values out and rewrite the above expression like the below:
= 1/5 x (4/1 - 15/1)
= 1/5 x (4 - 15)

step 7Simplify the above expression further:
= 1/5 x -11
= -11/5
4/5 - 3 = -11/5

Hence,
4/5 minus 3 as a fraction is -11/5.

4/5 - 3 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 4/5
Fraction B: 3/1

What to be found?
(4/5)-(3) = ?
Find what's the difference between 4/5 and 3.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (4 x 1), find the product of numerator of Fraction B and denominator of Fraction A (3 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:
= (4 x 1) - (3 x 5)/(5 x 1)

step 3 Simplify and rewrite the fraction:
= (4 - 15)/5
4/5 - 3 = -11/5

Hence,
4/5 minus 3 in fraction is -11/5
