Learn how to find what is 1/2 minus 2/39 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 2/39 as a fraction and decimal.
Summary: 1/2 minus 2/39 = 35/78
Since both fractions have unequal denominators, 1/2 minus 2/39 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/2 and fraction 2/39 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 2 and 39. 78 is the LCM of 2 and 39. Multiplying the LCM 78 with the numerators and denominators of both fractions (1/2 x 78/78) - (2/39 x 78/78), and simplify further in order to have the common denominator. So the equivalent fraction for 1/2 is 39/78 and for 2/39 is 4/78. By simplifying this fraction subtraction 39/78 - 4/78, it becomes 35/78.
Pie Chart Representation: 1/2 - 2/39 = 35/78
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/39 from 1/2. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/2 minus 2/39.
1. LCM method
2. Cross multiplication method.
(1/2) - (2/39) using LCM Method:
What is 1/2 minus 2/39 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/39
What to be found?
(1/2) - (2/39) = ?
Find what's the difference between 1/2 and 2/39.
step 2 Compare the denominators of fractions 1/2 and 2/39 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/39 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 1/2 and 2/39:
The LCM of 2 and 39 is 78.
step 4 Write the fractions 1/2 and 2/39 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/2 - 2/39
= [(1 x 78)/(2 x 78)] - [(2 x 78)/(39 x 78)]
step 5 Simplify the expression to have common denominator:
= 39/78 - 4/78
step 6 Take the common values out and rewrite the above expression like the below:
= 1/78 x (39/1 - 4/1)
= 1/78 x (39 - 4)
step 7Simplify the above expression further:
= 1/78 x 35
= 35/78
1/2 - 2/39 = 35/78
Hence,
1/2 minus 2/39 as a fraction is 35/78.
1/2 - 2/39 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/39
What to be found?
(1/2)-(2/39) = ?
Find what's the difference between 1/2 and 2/39.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 39), find the product of numerator of Fraction B and denominator of Fraction A (2 x 2), and find the product of both denominators of Fraction A and Fraction B (2 x 39) and rewrite the equation as like the below:
= (1 x 39) - (2 x 2)/(2 x 39)
step 3 Simplify and rewrite the fraction:
= (39 - 4)/78
1/2 - 2/39 = 35/78
Hence,
1/2 minus 2/39 in fraction is 35/78
