(12/5) - (7/20) using LCM Method:
What is 12/5 minus 7/20 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/5
Fraction B: 7/20

What to be found?
(12/5) - (7/20) = ?
Find what's the difference between 12/5 and 7/20.

step 2 Compare the denominators of fractions 12/5 and 7/20 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 12/5 and 7/20 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 12/5 and 7/20:
The LCM of 5 and 20 is 20.

step 4 Write the fractions 12/5 and 7/20 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/5 - 7/20
= [(12 x 20)/(5 x 20)] - [(7 x 20)/(20 x 20)]

step 5 Simplify the expression to have common denominator:
= 48/20 - 7/20

step 6 Take the common values out and rewrite the above expression like the below:
= 1/20 x (48/1 - 7/1)
= 1/20 x (48 - 7)

step 7Simplify the above expression further:
= 1/20 x 41
= 41/20
12/5 - 7/20 = 41/20

Hence,
12/5 minus 7/20 as a fraction is 41/20.
