2. Cross multiplication method.

(9/3) - (8/12) using LCM Method:
What is 9/3 minus 8/12 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/3
Fraction B: 8/12

What to be found?
(9/3) - (8/12) = ?
Find what's the difference between 9/3 and 8/12.

step 2 Compare the denominators of fractions 9/3 and 8/12 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/3 and 8/12 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 9/3 and 8/12:
The LCM of 3 and 12 is 12.

step 4 Write the fractions 9/3 and 8/12 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/3 - 8/12
= [(9 x 12)/(3 x 12)] - [(8 x 12)/(12 x 12)]

step 5 Simplify the expression to have common denominator:
= 36/12 - 8/12

step 6 Take the common values out and rewrite the above expression like the below:
= 1/12 x (36/1 - 8/1)
= 1/12 x (36 - 8)

step 7Simplify the above expression further:
= 1/12 x 28
= 28/12
= 7/3
9/3 - 8/12 = 7/3

Hence,
9/3 minus 8/12 as a fraction is 7/3.
