(6/7) - (15/16) using LCM Method:
What is 6/7 minus 15/16 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 15/16

What to be found?
(6/7) - (15/16) = ?
Find what's the difference between 6/7 and 15/16.

step 2 Compare the denominators of fractions 6/7 and 15/16 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 6/7 and 15/16 are not equal, it is said to be unlike fractions subtraction.

The LCM of 7 and 16 is 112.

step 4 Write the fractions 6/7 and 15/16 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 6/7 - 15/16
= [(6 x 112)/(7 x 112)] - [(15 x 112)/(16 x 112)]

step 5 Simplify the expression to have common denominator:
= 96/112 - 105/112

step 6 Take the common values out and rewrite the above expression like the below:
= 1/112 x (96/1 - 105/1)
= 1/112 x (96 - 105)

step 7Simplify the above expression further:
= 1/112 x -9
= -9/112
6/7 - 15/16 = -9/112
