Question

A 12-inch board is cut into sections that are 3/4 inches long each. How many sections can you make?

Answer 1

16

Explanation:

If you have a 12-inch board and you are making 3/4 inch long sections, and you want to know many times you can do that here.

You just need to take 12 and divide it by the 3/4, to see how many sections you can have.

`12 / (3)/(4)`

Change division to multiplication by taking the reciprocal (the flipping) of the second number:

`12 \cdot (4)/(3)`

Write 12 as a fraction:

`(12)/(1)\cdot (4)/(3)`

To multiply fractions, multiply straight across on top and straight across on bottom:

`((12)(4))/((1)(3))`

`(48)/(3)`
