(12/5) - (5/9) using LCM Method:
What is 12/5 minus 5/9 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 12/5
Fraction B: 5/9

What to be found?
(12/5) - (5/9) = ?
Find what's the difference between 12/5 and 5/9.

step 2 Compare the denominators of fractions 12/5 and 5/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 12/5 and 5/9 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 12/5 and 5/9:
The LCM of 5 and 9 is 45.

step 4 Write the fractions 12/5 and 5/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 12/5 - 5/9
= [(12 x 45)/(5 x 45)] - [(5 x 45)/(9 x 45)]

step 5 Simplify the expression to have common denominator:
= 108/45 - 25/45

step 6 Take the common values out and rewrite the above expression like the below:
= 1/45 x (108/1 - 25/1)
= 1/45 x (108 - 25)

step 7Simplify the above expression further:
= 1/45 x 83
= 83/45
12/5 - 5/9 = 83/45

Hence,
12/5 minus 5/9 as a fraction is 83/45.
