2. Cross multiplication method.

(2/17) - (18/5) using LCM Method:
What is 2/17 minus 18/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/17
Fraction B: 18/5

What to be found?
(2/17) - (18/5) = ?
Find what's the difference between 2/17 and 18/5.

step 2 Compare the denominators of fractions 2/17 and 18/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/17 and 18/5 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 2/17 and 18/5:
The LCM of 17 and 5 is 85.

step 4 Write the fractions 2/17 and 18/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/17 - 18/5
= [(2 x 85)/(17 x 85)] - [(18 x 85)/(5 x 85)]

step 5 Simplify the expression to have common denominator:
= 10/85 - 306/85

step 6 Take the common values out and rewrite the above expression like the below:
= 1/85 x (10/1 - 306/1)
= 1/85 x (10 - 306)

step 7Simplify the above expression further:
= 1/85 x -296
= -296/85
2/17 - 18/5 = -296/85

Hence,
2/17 minus 18/5 as a fraction is -296/85.
