(9/7) - (3/8) using LCM Method:
What is 9/7 minus 3/8 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 9/7
Fraction B: 3/8

What to be found?
(9/7) - (3/8) = ?
Find what's the difference between 9/7 and 3/8.

step 2 Compare the denominators of fractions 9/7 and 3/8 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9/7 and 3/8 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 9/7 and 3/8:
The LCM of 7 and 8 is 56.

step 4 Write the fractions 9/7 and 3/8 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9/7 - 3/8
= [(9 x 56)/(7 x 56)] - [(3 x 56)/(8 x 56)]

step 5 Simplify the expression to have common denominator:
= 72/56 - 21/56

step 6 Take the common values out and rewrite the above expression like the below:
= 1/56 x (72/1 - 21/1)
= 1/56 x (72 - 21)

step 7Simplify the above expression further:
= 1/56 x 51
= 51/56
9/7 - 3/8 = 51/56

Hence,
9/7 minus 3/8 as a fraction is 51/56.
