What is 3/4 minus 9/2 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 3/4
Fraction B: 9/2

What to be found?
3/4-9/2 = ?
Find what's the difference between 3/4 and 9/2.

step 2 Compare the denominators of fractions 3/4 and 9/2 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 3/4 and 9/2 are not equal, it is said to be unlike fractions subtraction.

The LCM of 4 and 2 is 4.

step 4 Write the fractions 3/4 and 9/2 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
=3/4-9/2
=(3 x 4)/(4 x 4)-(9 x 4)/(2 x 4)

step 5 Simplify the expression to have common denominator:
=3/4-18/4

step 6 Take the common values out and rewrite the above expression like the below:
=1/4 x (3/1-18/1)
=1/4 x (3 - 18)

step 7Simplify the above expression further:
=1/4 x -15
=-15/4
3/4-9/2=-15/4

Hence,
3/4 minus 9/2 equals to -15/4 in fraction.
