1 - 2/4 as a fraction

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

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

Pie Chart Representation: 1 - 2/4 = 1/2

CALCULATION: 1 - 2/4 as a fraction
1 - 2/4 = (?)
1/1 - 2/4 = [(1 x 4) - (2 x 1)]/(1 x 4)
= (4 - 2)/4
= 2/4
= (2 x 1)/(2 x 2)
= 1/2
1 - 2/4 = 1/2
1 minus 2/4 as a fraction is 1/2.

where
1 is a whole number as a minuend,
2/4 is a proper fraction as a subtrahend,
1/2 is the difference between 1 and 2/4.

where
0.5 is the difference between 1 and 2/4.

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

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

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

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

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

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

step 5 Simplify the expression to have common denominator:
= 4/4 - 2/4

step 6 Take the common values out and rewrite the above expression like the below:
= 1/4 x (4/1 - 2/1)
= 1/4 x (4 - 2)

step 7Simplify the above expression further:
= 1/4 x 2
= 2/4
= 1/2
1 - 2/4 = 1/2

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

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

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

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

step 3 Simplify and rewrite the fraction:
= (4 - 2)/4
= 2/4
= 1/2
1 - 2/4 = 1/2

Hence,
1 minus 2/4 in fraction is 1/2
