2. Cross multiplication method.

(2/5) - (1/72) using LCM Method:
What is 2/5 minus 1/72 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/72

What to be found?
(2/5) - (1/72) = ?
Find what's the difference between 2/5 and 1/72.

step 2 Compare the denominators of fractions 2/5 and 1/72 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/72 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 1/72:
The LCM of 5 and 72 is 360.

step 4 Write the fractions 2/5 and 1/72 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 - 1/72
= [(2 x 360)/(5 x 360)] - [(1 x 360)/(72 x 360)]

step 5 Simplify the expression to have common denominator:
= 144/360 - 5/360

step 6 Take the common values out and rewrite the above expression like the below:
= 1/360 x (144/1 - 5/1)
= 1/360 x (144 - 5)

step 7Simplify the above expression further:
= 1/360 x 139
= 139/360
2/5 - 1/72 = 139/360

Hence,
2/5 minus 1/72 as a fraction is 139/360.
