(17/7) - (2/13) using LCM Method:
What is 17/7 minus 2/13 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/7
Fraction B: 2/13

What to be found?
(17/7) - (2/13) = ?
Find what's the difference between 17/7 and 2/13.

step 2 Compare the denominators of fractions 17/7 and 2/13 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 17/7 and 2/13 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 17/7 and 2/13:
The LCM of 7 and 13 is 91.

step 4 Write the fractions 17/7 and 2/13 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/7 - 2/13
= [(17 x 91)/(7 x 91)] - [(2 x 91)/(13 x 91)]

step 5 Simplify the expression to have common denominator:
= 221/91 - 14/91

step 6 Take the common values out and rewrite the above expression like the below:
= 1/91 x (221/1 - 14/1)
= 1/91 x (221 - 14)

step 7Simplify the above expression further:
= 1/91 x 207
= 207/91
17/7 - 2/13 = 207/91

Hence,
17/7 minus 2/13 as a fraction is 207/91.
