What is 2/5 minus 1/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/8

What to be found?
2/5-1/8 = ?
Find what's the difference between 2/5 and 1/8.

step 2 Compare the denominators of fractions 2/5 and 1/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/8 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 2/5 and 1/8:
The LCM of 5 and 8 is 40.

step 4 Write the fractions 2/5 and 1/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=2/5-1/8
=(2 x 40)/(5 x 40)-(1 x 40)/(8 x 40)

step 5 Simplify the expression to have common denominator:
=16/40-5/40

step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (16/1-5/1)
=1/40 x (16 - 5)

step 7Simplify the above expression further:
=1/40 x 11
=11/40
2/5-1/8=11/40

Hence,
2/5 minus 1/8 equals to 11/40 in fraction.

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/8

What to be found?
2/5-1/8 = ?
Find what's the difference between 2/5 and 1/8.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (2 x 8), find the product of numerator of Fraction B and denominator of Fraction A (1 x 5), and find the product of both denominators of Fraction A and Fraction B (5 x 8) and rewrite the equation as like the below:
= (2 x 8) - (1 x 5)/(5 x 8)

step 3 Simplify and rewrite the fraction:
= (16 - 5)/40
2/5-1/8 = 11/40
Hence,
2/5 minus 1/8 = 11/40
