Today in math class, we learned more about dividing fractions.

Mr. Harbeck assigned us some questions for homework:

3/4 / 1/8
5 / 1/4
9/10 / 12
5/8 / 3/10

As you can see, you can use a ratio table to answer this question. After finding out the answer, you have to make it a "reciprocal". Once you find the answer using the reciprocal, you must simplify it in lowest terms.

Whatever you did on one side of the ratio table, you must do on the other side of the ratio table. You do the same thing for this question too. You have to make it a reciprocal. So 5/1 x 4/1 = 20/1.

You can also simply just switch the denominator and the numerator too, like shown in this question. 9/10 was turned into a reciprocal, which would be 10/9. 10/9 x 12/1 = 120/9 You have to simplify this to lowest terms too.

Same thing for this one too, you make 3/10 into a reciprocal. You also have to simplify it in lowest terms.

Reciprocal: When you switch the denominator to the numerator, and the numerator to the denominator.
