What is 1/9 minus 1/3 as a fraction?
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/9
Fraction B: 1/3
What to be found?
1/9-1/3 = ?
Find what's the difference between 1/9 and 1/3.
step 2 Compare the denominators of fractions 1/9 and 1/3 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/9 and 1/3 are not equal, it is said to be unlike fractions subtraction.

=1/9-1/3
=(1 x 9)/(9 x 9)-(1 x 9)/(3 x 9)
step 5 Simplify the expression to have common denominator:
=1/9-3/9
step 6 Take the common values out and rewrite the above expression like the below:
=1/9 x (1/1-3/1)
=1/9 x (1 - 3)
step 7Simplify the above expression further:
=1/9 x -2
=-2/9
1/9-1/3=-2/9
Hence,
1/9 minus 1/3 equals to -2/9 in fraction.
