Example Question #1 : Operations

Machine A can produce 4 buttons in 2 days.  Machine B can produce 20 buttons in 4 days.  How many buttons can Machine A and B, working together, produce in 40 days?

Possible Answers:

\dpi{100} 70

\dpi{100} 280

\dpi{100} 200

\dpi{100} 7

Correct answer:

\dpi{100} 280

Explanation:

First determine how many buttons each machine can produce in a day.

Machine A: \dpi{100} \frac{4}{2}=2\ buttons\ per\ day

Machine B: \dpi{100} \frac{20}{4}=5\ buttons\ per\ day

Machine A and B can produce 7 buttons per day when they are working together.

\dpi{100} 7\times 40=280\ buttons

Example Question #2 : Operations

Brian has 3 siblings.  When his family orders pizza, each of the 4 children is given \dpi{100} \frac{1}{4} of the pizza.  Brian does not feel well so he only finishes \dpi{100} \frac{1}{3} of his pizza.  If the original pizza consisted of 12 slices of pizza, how many slices did Brian eat?

Possible Answers:

\dpi{100} 6

\dpi{100} 3

\dpi{100} 4

\dpi{100} 1

Correct answer:

\dpi{100} 1

Explanation:

Brian eats \dpi{100} \frac{1}{3}\times \frac{1}{4}\times 12\ slices\ of\ pizza.

So Brian eats

\dpi{100} \frac{1}{12}\cdot 12=1\ slice\ of\ pizza.
