QUESTION: 11

A baker made 20 pies. A Boy Scout troop buys one-fourth of his pies, a preschool teacher buys one-third of his pies, and a caterer buys one-sixth of his pies.
How many pies does the baker have left?

3/4
15
12
5

Answer(s): D

Explanation:

Convert the different denominators to a common denominator that all the denominators can divide into evenly.
4, 3, and 6 all divide evenly into 12.
To convert 1/4 to x/12, divide 12 (the new common denominator) by 4 (the old common denominator) to get 3.
Then multiply 1/4 by 3/3 (another way of saying 1).
Do the same calculation for the other fractions: 1/3 = 4/12 and 1/6 = 2/12.
Then add the new numerators together: 3 + 4 + 2 = 9.
This gives you your new added numerator.
Place the added numerator over the new denominator, and you can see that 9/12 of the pies have been sold.
9/12 can be reduced to 3/4.
3/4 or 75% of the pies have been sold.
20 × 0.75 = 15.
15 of 20 pies have been sold.
20 15 = 5 pies remaining

$1.50
$8.00
$22.50

Answer(s): A

QUESTION: 13

A security guard walks the equivalent of six city blocks when he makes a circuit around the building.
If he walks at a pace of eight city blocks every 30 minutes, how long will it take him to complete a circuit around the building, assuming he doesn't run into any thieves?

20.00 minutes
3.75 minutes
22.50 minutes
24.00 minutes

Answer(s): C

Explanation:

Divide 30 by 8 to determine that the security guard takes 3.75 minutes to walk one city block. Multiply 3.75 by 6, the number of blocks it takes to complete the circuit, to arrive at 22.50, or 221/2 minutes.

QUESTION: 14

The population of Grand Island, Nebraska, grew by 600,000 people between 1995 and 2005, one-fifth more than the town council predicted.
The town council originally predicted the city's population would grow by __________.

400,000
500,000
300,000
200,000

Answer(s): B

Explanation:

Let x = the original estimate. An additional one-fifth would be 6/5x, or 120% of x.
The equation can be expressed as 1.2x = 600000.
To solve for x, divide both sides of the equation by 1.2.
x = 500,000.
