(14/9) - (12/5) using LCM Method:
What is 14/9 minus 12/5 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 14/9
Fraction B: 12/5

What to be found?
(14/9) - (12/5) = ?
Find what's the difference between 14/9 and 12/5.

step 2 Compare the denominators of fractions 14/9 and 12/5 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 14/9 and 12/5 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 14/9 and 12/5:
The LCM of 9 and 5 is 45.

step 4 Write the fractions 14/9 and 12/5 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 14/9 - 12/5
= [(14 x 45)/(9 x 45)] - [(12 x 45)/(5 x 45)]

step 5 Simplify the expression to have common denominator:
= 70/45 - 108/45

step 6 Take the common values out and rewrite the above expression like the below:
= 1/45 x (70/1 - 108/1)
= 1/45 x (70 - 108)

step 7Simplify the above expression further:
= 1/45 x -38
= -38/45
14/9 - 12/5 = -38/45

Hence,
14/9 minus 12/5 as a fraction is -38/45.
