Just starting the 2nd 9-weeks and I have already messed up. Yesterday we learned how to multiply fractions by fractions and reviewed how to simplify our answers. Well it seems that I forgot to teach everyone how to multiply fractions by a whole number.

So guess what we are doing today? Yep, we are multiplying fractions and whole numbers.

For example, with 5 x 1/3 you first have to change 5 to 5/1 and then multiply by 1/3. First you multiply the numerators and then multiply the denominators. You will get 5/3.

This is an improper fraction and must be turned into a mixed number.

Not every problem will be like this. If the problem was 3 x 1/8 that would be 3/8. This answer is already simplified.
