Question

Each salt shaker holds 1 1/4 ounces. If a box of salt contains 10 ounces, how many shakers will it fit

Answer 1

Well to do this you've got to divide 10 by 1 1/4, so you're going to want to turn both into mixed numbers.

10 is 10/1, and 1 1/4 will be 5/4.  Now you can divide 10/1 by 5/4.

In order to divide fractions, you have to use the inverse operations to get the answer -- flip it all around.

10/1 stays the same, but the division sign and 5/4 get flipped.  This turns the problem into 10/1 * 4/5

10/1 * 4/5 will equal 40/5, and to simplify you just have to divide that.  40 / 5 = 8, so you can fit 8 shakers worth of salt into this box.

Answer 2

8 shakers will fit  becuase 4 shakers equal 5 ounces and you multiply it by two and you get 10
