2. Cross multiplication method.

(2/5) - (1/84) using LCM Method:
What is 2/5 minus 1/84 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/84

What to be found?
(2/5) - (1/84) = ?
Find what's the difference between 2/5 and 1/84.

step 2 Compare the denominators of fractions 2/5 and 1/84 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/84 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 2/5 and 1/84:
The LCM of 5 and 84 is 420.

step 4 Write the fractions 2/5 and 1/84 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 - 1/84
= [(2 x 420)/(5 x 420)] - [(1 x 420)/(84 x 420)]

step 5 Simplify the expression to have common denominator:
= 168/420 - 5/420

step 6 Take the common values out and rewrite the above expression like the below:
= 1/420 x (168/1 - 5/1)
= 1/420 x (168 - 5)

step 7Simplify the above expression further:
= 1/420 x 163
= 163/420
2/5 - 1/84 = 163/420

Hence,
2/5 minus 1/84 as a fraction is 163/420.
