a strip of paper is 9/10 of an inch long. you need to cut the paper into 3/12 inch pieces. how many pieces will you be able to c

e-lub [12.9K]

We have to divide 9/10 by 3/12.

if we divide by a fraction, we can instead multiply by it's inverse:

$\frac{9}{12}/ \frac{3}{12} = \frac{9}{12} * \frac{12}{3}$

so now we count:

$\frac{9}{12} * \frac{12}{3} =\frac{9}{1} * \frac{1}{3}=3$

so we can cut exactly 3 pieces!
