1/4 - 2/80 as a fraction

Learn how to find what is 1/4 minus 2/80 in fraction form just in a few minutes. We have covered the easiest method to write 1/4 - 2/80 as a fraction and decimal.

Summary: 1/4 minus 2/80 = 9/40
Since both fractions have unequal denominators, 1/4 minus 2/80 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/4 and fraction 2/80 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 4 and 80. 80 is the LCM of 4 and 80. Multiplying the LCM 80 with the numerators and denominators of both fractions (1/4 x 80/80) - (2/80 x 80/80), and simplify further in order to have the common denominator. So the equivalent fraction for 1/4 is 20/80 and for 2/80 is 2/80. By simplifying this fraction subtraction 20/80 - 2/80, it becomes 18/80.

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/80 from 1/4. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/4 minus 2/80.
1. LCM method
2. Cross multiplication method.

(1/4) - (2/80) using LCM Method:
What is 1/4 minus 2/80 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/4
Fraction B: 2/80

What to be found?
(1/4) - (2/80) = ?
Find what's the difference between 1/4 and 2/80.

step 2 Compare the denominators of fractions 1/4 and 2/80 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/4 and 2/80 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 1/4 and 2/80:
The LCM of 4 and 80 is 80.

step 4 Write the fractions 1/4 and 2/80 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/4 - 2/80
= [(1 x 80)/(4 x 80)] - [(2 x 80)/(80 x 80)]

step 5 Simplify the expression to have common denominator:
= 20/80 - 2/80

step 6 Take the common values out and rewrite the above expression like the below:
= 1/80 x (20/1 - 2/1)
= 1/80 x (20 - 2)

step 7Simplify the above expression further:
= 1/80 x 18
= 18/80
= 9/40
1/4 - 2/80 = 9/40

Hence,
1/4 minus 2/80 as a fraction is 9/40.

1/4 - 2/80 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/4
Fraction B: 2/80

What to be found?
(1/4)-(2/80) = ?
Find what's the difference between 1/4 and 2/80.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 80), find the product of numerator of Fraction B and denominator of Fraction A (2 x 4), and find the product of both denominators of Fraction A and Fraction B (4 x 80) and rewrite the equation as like the below:
= (1 x 80) - (2 x 4)/(4 x 80)

step 3 Simplify and rewrite the fraction:
= (80 - 8)/320
= 72/320
= 9/40
