1/5 - 4/19 as a fraction

Learn how to find what is 1/5 minus 4/19 in fraction form just in a few minutes. We have covered the easiest method to write 1/5 - 4/19 as a fraction and decimal.

Summary: 1/5 minus 4/19 = -1/95
Since both fractions have unequal denominators, 1/5 minus 4/19 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/5 and fraction 4/19 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 5 and 19. 95 is the LCM of 5 and 19. Multiplying the LCM 95 with the numerators and denominators of both fractions (1/5 x 95/95) - (4/19 x 95/95), and simplify further in order to have the common denominator. So the equivalent fraction for 1/5 is 19/95 and for 4/19 is 20/95. By simplifying this fraction subtraction 19/95 - 20/95, it becomes -1/95.

2. Cross multiplication method.

(1/5) - (4/19) using LCM Method:
What is 1/5 minus 4/19 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/5
Fraction B: 4/19

What to be found?
(1/5) - (4/19) = ?
Find what's the difference between 1/5 and 4/19.

step 2 Compare the denominators of fractions 1/5 and 4/19 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/5 and 4/19 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 1/5 and 4/19:
The LCM of 5 and 19 is 95.

step 4 Write the fractions 1/5 and 4/19 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/5 - 4/19
= [(1 x 95)/(5 x 95)] - [(4 x 95)/(19 x 95)]

step 5 Simplify the expression to have common denominator:
= 19/95 - 20/95

step 6 Take the common values out and rewrite the above expression like the below:
= 1/95 x (19/1 - 20/1)
= 1/95 x (19 - 20)

step 7Simplify the above expression further:
= 1/95 x -1
= -1/95
1/5 - 4/19 = -1/95

Hence,
1/5 minus 4/19 as a fraction is -1/95.
