2. Cross multiplication method.

(13/6) - (7/15) using LCM Method:
What is 13/6 minus 7/15 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 13/6
Fraction B: 7/15

What to be found?
(13/6) - (7/15) = ?
Find what's the difference between 13/6 and 7/15.

step 2 Compare the denominators of fractions 13/6 and 7/15 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 13/6 and 7/15 are not equal, it is said to be unlike fractions subtraction.

The LCM of 6 and 15 is 30.

step 4 Write the fractions 13/6 and 7/15 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 13/6 - 7/15
= [(13 x 30)/(6 x 30)] - [(7 x 30)/(15 x 30)]

step 5 Simplify the expression to have common denominator:
= 65/30 - 14/30

step 6 Take the common values out and rewrite the above expression like the below:
= 1/30 x (65/1 - 14/1)
= 1/30 x (65 - 14)

step 7Simplify the above expression further:
= 1/30 x 51
= 51/30
= 17/10
13/6 - 7/15 = 17/10

Hence,
