(8/9) - (7/3) using LCM Method:
What is 8/9 minus 7/3 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 8/9
Fraction B: 7/3

What to be found?
(8/9) - (7/3) = ?
Find what's the difference between 8/9 and 7/3.

step 2 Compare the denominators of fractions 8/9 and 7/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 8/9 and 7/3 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 8/9 and 7/3:
The LCM of 9 and 3 is 9.

step 4 Write the fractions 8/9 and 7/3 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 8/9 - 7/3
= [(8 x 9)/(9 x 9)] - [(7 x 9)/(3 x 9)]

= 8/9 - 21/9

step 6 Take the common values out and rewrite the above expression like the below:
= 1/9 x (8/1 - 21/1)
= 1/9 x (8 - 21)

step 7Simplify the above expression further:
= 1/9 x -13
= -13/9
8/9 - 7/3 = -13/9

Hence,
8/9 minus 7/3 as a fraction is -13/9.
