What is 45 over 12 changed into a mixed number?

Answer 1

To convert a vulgar fraction into a mixed number, you need to subtract the denominator from the numerator a certain number of times such that the numerator is less than the denominator. In the case of 45/12, we can subtract 12 from 45 three times to leave us with 9/12. Both these numbers can be divided by 3, so we can simplify it to 3/4. We subtracted 12 three times so need to write that as the units. Thus, as a mixed number, 45/12 would be 3 and 3/4.
