2. Cross multiplication method.

(2/45) - (1/80) using LCM Method:
What is 2/45 minus 1/80 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 2/45
Fraction B: 1/80

What to be found?
(2/45) - (1/80) = ?
Find what's the difference between 2/45 and 1/80.

step 2 Compare the denominators of fractions 2/45 and 1/80 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 2/45 and 1/80 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 2/45 and 1/80:
The LCM of 45 and 80 is 720.

step 4 Write the fractions 2/45 and 1/80 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 2/45 - 1/80
= [(2 x 720)/(45 x 720)] - [(1 x 720)/(80 x 720)]

step 5 Simplify the expression to have common denominator:
= 32/720 - 9/720

step 6 Take the common values out and rewrite the above expression like the below:
= 1/720 x (32/1 - 9/1)
= 1/720 x (32 - 9)

step 7Simplify the above expression further:
= 1/720 x 23
= 23/720
2/45 - 1/80 = 23/720

Hence,
2/45 minus 1/80 as a fraction is 23/720.
