2. Cross multiplication method.

(2/5) - (1/64) using LCM Method:
What is 2/5 minus 1/64 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/5
Fraction B: 1/64

What to be found?
(2/5) - (1/64) = ?
Find what's the difference between 2/5 and 1/64.

step 2 Compare the denominators of fractions 2/5 and 1/64 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/5 and 1/64 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 1/64:
The LCM of 5 and 64 is 320.

step 4 Write the fractions 2/5 and 1/64 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/5 - 1/64
= [(2 x 320)/(5 x 320)] - [(1 x 320)/(64 x 320)]

step 5 Simplify the expression to have common denominator:
= 128/320 - 5/320

step 6 Take the common values out and rewrite the above expression like the below:
= 1/320 x (128/1 - 5/1)
= 1/320 x (128 - 5)

step 7Simplify the above expression further:
= 1/320 x 123
= 123/320
2/5 - 1/64 = 123/320

Hence,
2/5 minus 1/64 as a fraction is 123/320.
