Learn how to find what is 1/2 minus 2/19 in fraction form just in a few minutes. We have covered the easiest method to write 1/2 - 2/19 as a fraction and decimal.
Summary: 1/2 minus 2/19
Since both the fractions have the unequal denominators, you have to find the equivalent fractions for 1/2 and 2/19 having identical denominators before starting adding the fractions. Find the LCM of denominators, 38 is the LCM of 2 and 19. Multiply the LCM 38 with all the numerators and denominators of both fractions (1/2 x 38/38) - (2/19 x 38/38) and simplify further in order to have the common denominators. By simplifying the fraction subtraction expression becomes 15/38.
The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 2/19 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 2/19.
1. LCM method
2. Cross multiplication method.
1/2-2/19 using LCM Method:
What is 1/2 minus 2/19 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/19
What to be found?
1/2-2/19 = ?
Find what's the difference between 1/2 and 2/19.
step 2 Compare the denominators of fractions 1/2 and 2/19 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/2 and 2/19 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 2/19:
The LCM of 2 and 19 is 38.
step 4 Write the fractions 1/2 and 2/19 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=1/2-2/19
=(1 x 38)/(2 x 38)-(2 x 38)/(19 x 38)
step 5 Simplify the expression to have common denominator:
=19/38-4/38
step 6 Take the common values out and rewrite the above expression like the below:
=1/38 x (19/1-4/1)
=1/38 x (19 - 4)
step 7Simplify the above expression further:
=1/38 x 15
=15/38
1/2-2/19=15/38
Hence,
1/2 minus 2/19 equals to 15/38 in fraction.
1/2-2/19 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/2
Fraction B: 2/19
What to be found?
1/2-2/19 = ?
Find what's the difference between 1/2 and 2/19.
step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 19), 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 19) and rewrite the equation as like the below:
= (1 x 19) - (2 x 2)/(2 x 19)
step 3 Simplify and rewrite the fraction:
= (19 - 4)/38
1/2-2/19 = 15/38
Hence,
1/2 minus 2/19 = 15/38
