Answer:
a. 15/16 tons or 0.9375 tons
b. 6 4/5 work days or 6.8 work days
Step-by-step explanation:
a.
there are 3 hours between 9am and noon
rewrite 2 1/2 as 5/2 or 2.5
make a proportion: [tex]\frac{5/2}{8} = \frac{x}{3}[/tex]
cross multiply: 5/2 * 3 = 8x →15/2 = 8x
divide 15/2 by 8 = 15/2 * 1/8 = 15/16
b. make another proportion
[tex]\frac{5/2}{8} = \frac{17}{y}[/tex]
cross multiply:(5/2) y = 8*17 → (5/2) y = 136
divide 136 by 5/2 = 136 * 2/5 =54 2/5 hours
1 work day = 8 hours
so 54 2/5 hours / 8 hours = 6 4/5 work days or 6.8 work days
