(5/7) - (13/3) using LCM Method:
What is 5/7 minus 13/3 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 5/7
Fraction B: 13/3

What to be found?
(5/7) - (13/3) = ?
Find what's the difference between 5/7 and 13/3.

step 2 Compare the denominators of fractions 5/7 and 13/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 5/7 and 13/3 are not equal, it is said to be unlike fractions subtraction.

The LCM of 7 and 3 is 21.

step 4 Write the fractions 5/7 and 13/3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 5/7 - 13/3
= [(5 x 21)/(7 x 21)] - [(13 x 21)/(3 x 21)]

step 5 Simplify the expression to have common denominator:
= 15/21 - 91/21

step 6 Take the common values out and rewrite the above expression like the below:
= 1/21 x (15/1 - 91/1)
= 1/21 x (15 - 91)

step 7Simplify the above expression further:
= 1/21 x -76
= -76/21
5/7 - 13/3 = -76/21

Hence,
5/7 minus 13/3 as a fraction is -76/21.
