Cherries cost $4.99 per pound ($4.99/lb). This is the ratio of interest. Lacey buys 3.5 pounds. We can determine how much she will pay for the cherries using a conversion fraction.
3.5 lb × ($4.99/lb) = $17.47 ≈ $17 (rounding off to 2 significant figures)
I dont think so because if you multiply 2 1/2 by 5/6 you would get 2 1/12 which means that you can make the first shelf but you would need to subtract 2 1/2 minus 2 1/12 and you would get 5/12. And 5/12 is not the same as 4/5
