Answer:
16
Step-by-step 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.
[tex]12 \div \frac{3}{4}[/tex]
Change division to multiplication by taking the reciprocal (the flipping) of the second number:
[tex]12 \cdot \frac{4}{3}[/tex]
Write 12 as a fraction:
[tex]\frac{12}{1}\cdot \frac{4}{3}[/tex]
To multiply fractions, multiply straight across on top and straight across on bottom:
[tex]\frac{(12)(4)}{(1)(3)}[/tex]
[tex]\frac{48}{3}[/tex]
16
