What is 1/3 minus 3/9 as a fraction?

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

What to be found?
1/3-3/9 = ?
Find what's the difference between 1/3 and 3/9.

step 2 Compare the denominators of fractions 1/3 and 3/9 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/3 and 3/9 are not equal, it is said to be unlike fractions subtraction.
