(6/7) - (17/10) using LCM Method:
What is 6/7 minus 17/10 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 6/7
Fraction B: 17/10

What to be found?
(6/7) - (17/10) = ?
Find what's the difference between 6/7 and 17/10.

step 2 Compare the denominators of fractions 6/7 and 17/10 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 6/7 and 17/10 are not equal, it is said to be unlike fractions subtraction.

The LCM of 7 and 10 is 70.

step 4 Write the fractions 6/7 and 17/10 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 6/7 - 17/10
= [(6 x 70)/(7 x 70)] - [(17 x 70)/(10 x 70)]

step 5 Simplify the expression to have common denominator:
= 60/70 - 119/70

step 6 Take the common values out and rewrite the above expression like the below:
= 1/70 x (60/1 - 119/1)
= 1/70 x (60 - 119)

step 7Simplify the above expression further:
= 1/70 x -59
= -59/70
6/7 - 17/10 = -59/70

Hence,
6/7 minus 17/10 as a fraction is -59/70.
