(13/7) - (5/4) using LCM Method:
What is 13/7 minus 5/4 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/7
Fraction B: 5/4

What to be found?
(13/7) - (5/4) = ?
Find what's the difference between 13/7 and 5/4.

step 2 Compare the denominators of fractions 13/7 and 5/4 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/7 and 5/4 are not equal, it is said to be unlike fractions subtraction.

The LCM of 7 and 4 is 28.

step 4 Write the fractions 13/7 and 5/4 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/7 - 5/4
= [(13 x 28)/(7 x 28)] - [(5 x 28)/(4 x 28)]

step 5 Simplify the expression to have common denominator:
= 52/28 - 35/28

step 6 Take the common values out and rewrite the above expression like the below:
= 1/28 x (52/1 - 35/1)
= 1/28 x (52 - 35)

step 7Simplify the above expression further:
= 1/28 x 17
= 17/28
13/7 - 5/4 = 17/28

Hence,
13/7 minus 5/4 as a fraction is 17/28.
