(7/4) - (3/13) using LCM Method:
What is 7/4 minus 3/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 7/4
Fraction B: 3/13

What to be found?
(7/4) - (3/13) = ?
Find what's the difference between 7/4 and 3/13.

step 2 Compare the denominators of fractions 7/4 and 3/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 7/4 and 3/13 are not equal, it is said to be unlike fractions subtraction.

The LCM of 4 and 13 is 52.

step 4 Write the fractions 7/4 and 3/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 7/4 - 3/13
= [(7 x 52)/(4 x 52)] - [(3 x 52)/(13 x 52)]

step 5 Simplify the expression to have common denominator:
= 91/52 - 12/52

step 6 Take the common values out and rewrite the above expression like the below:
= 1/52 x (91/1 - 12/1)
= 1/52 x (91 - 12)

step 7Simplify the above expression further:
= 1/52 x 79
= 79/52
7/4 - 3/13 = 79/52

Hence,
7/4 minus 3/13 as a fraction is 79/52.
