Answer:
1/12
Step-by-step explanation:
1/3 - 1/4 can't be subtracted, so you have to find the least common multiple between 3 and 4, which is 12. When you change the denominators to 12, you have to multiply the numerator by the number needed to multiply with the denominator to make 12. So 1/3 would become 4/12, because 3 x 4 is 12 and 1/4 would become 3/12, because 4 x 3 is 12.
4/12 - 3/12 = 1/12
