2. Cross multiplication method.

(13/2) - (13) using LCM Method:
What is 13/2 minus 13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/2
Fraction B: 13/1

What to be found?
(13/2) - (13) = ?
Find what's the difference between 13/2 and 13.

step 2 Compare the denominators of fractions 13/2 and 13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/2 and 13 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 13/2 and 13:
The LCM of 2 and 1 is 2.

step 4 Write the fractions 13/2 and 13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/2 - 13
= [(13 x 2)/(2 x 2)] - [(13 x 2)/(1 x 2)]

step 5 Simplify the expression to have common denominator:
= 13/2 - 26/2

step 6 Take the common values out and rewrite the above expression like the below:
= 1/2 x (13/1 - 26/1)
= 1/2 x (13 - 26)

step 7Simplify the above expression further:
= 1/2 x -13
= -13/2
13/2 - 13 = -13/2

Hence,
13/2 minus 13 as a fraction is -13/2.
