Cristina bought a bag of coffee for $8.47. The weight of the bag was 7/8 of a pound. What was the price, per pound, of the coffe

SpyIntel [72]

~For this problem, you need to divide.
~The easy way that I think might help you is if you change the fraction into a decimal.

$\frac{7}{8} = 0.875$

Now divide $8.47 by 0.875
$\frac{8.47}{0.875} = 9.68$

The price per pound of the coffee was $9.68
