What is 3/8 minus 3/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/8
Fraction B: 3/10

What to be found?
3/8-3/10 = ?
Find what's the difference between 3/8 and 3/10.

step 2 Compare the denominators of fractions 3/8 and 3/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/8 and 3/10 are not equal, it is said to be unlike fractions subtraction.

=15/40-12/40

step 6 Take the common values out and rewrite the above expression like the below:
=1/40 x (15/1-12/1)
=1/40 x (15 - 12)

step 7Simplify the above expression further:
=1/40 x 3
=3/40
3/8-3/10=3/40

Hence,
3/8 minus 3/10 equals to 3/40 in fraction.

Input:
Fraction A: 3/8
Fraction B: 3/10

What to be found?
3/8-3/10 = ?
Find what's the difference between 3/8 and 3/10.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (3 x 10), find the product of numerator of Fraction B and denominator of Fraction A (3 x 8), and find the product of both denominators of Fraction A and Fraction B (8 x 10) and rewrite the equation as like the below:
= (3 x 10) - (3 x 8)/(8 x 10)

step 3 Simplify and rewrite the fraction:
= (30 - 24)/80
= 6/80
= 3/40
3/8-3/10 = 3/40
Hence,
