9 - 8/9 as a fraction

Learn how to find what is 9 minus 8/9 in fraction form just in a few minutes. We have covered the easiest method to write 9 - 8/9 as a fraction and decimal.

Summary: 9 minus 8/9 = 73/9
Since both fractions have unequal denominators, 9 minus 8/9 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 9 and fraction 8/9 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 9. 9 is the LCM of 1 and 9. Multiplying the LCM 9 with the numerators and denominators of both fractions (9 x 9/9) - (8/9 x 9/9), and simplify further in order to have the common denominator. So the equivalent fraction for 9 is 81/9 and for 8/9 is 8/9. By simplifying this fraction subtraction 81/9 - 8/9, it becomes 73/9.

2. Cross multiplication method.

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

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

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

step 2 Compare the denominators of fractions 9 and 8/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 9 and 8/9 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 9 and 8/9:
The LCM of 1 and 9 is 9.

step 4 Write the fractions 9 and 8/9 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 9 - 8/9
= [(9 x 9)/(1 x 9)] - [(8 x 9)/(9 x 9)]

step 5 Simplify the expression to have common denominator:
= 81/9 - 8/9

step 6 Take the common values out and rewrite the above expression like the below:
= 1/9 x (81/1 - 8/1)
= 1/9 x (81 - 8)

step 7Simplify the above expression further:
= 1/9 x 73
= 73/9
9 - 8/9 = 73/9

Hence,
9 minus 8/9 as a fraction is 73/9.
