2. Cross multiplication method.

(17/8) - (3/7) using LCM Method:
What is 17/8 minus 3/7 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 17/8
Fraction B: 3/7

What to be found?
(17/8) - (3/7) = ?
Find what's the difference between 17/8 and 3/7.

step 2 Compare the denominators of fractions 17/8 and 3/7 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 17/8 and 3/7 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 17/8 and 3/7:
The LCM of 8 and 7 is 56.

step 4 Write the fractions 17/8 and 3/7 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 17/8 - 3/7
= [(17 x 56)/(8 x 56)] - [(3 x 56)/(7 x 56)]

step 5 Simplify the expression to have common denominator:
= 119/56 - 24/56

step 6 Take the common values out and rewrite the above expression like the below:
= 1/56 x (119/1 - 24/1)
= 1/56 x (119 - 24)

step 7Simplify the above expression further:
= 1/56 x 95
= 95/56
17/8 - 3/7 = 95/56

Hence,
17/8 minus 3/7 as a fraction is 95/56.
