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
