Question 1

Convert the decimal to a percent.&#10;2.8&#10;A) 280%&#10;B) 0.0028%&#10;C) 0.28%&#10;D) 28%

Accepted Answer

To convert a decimal to a percent, multiply by 100. Thus, 2.8 * 100 = 280%.

Question 2

Perform the indicated operations.&#10;Add 92.48 + 94.88 + 18.789.&#10;A) 206.249&#10;B) 206.159&#10;C) 206.149&#10;D) 207.149

Accepted Answer

206.149

Question 3

Solve the problem.&#10;Find 75% of 96.&#10;A) 12.8&#10;B) 72&#10;C) 720&#10;D) 8

Accepted Answer

To find 75% of 96, we can multiply 96 by 0.75, which equals 72. Therefore, the answer is choice B. To find 75% of 96, we can multiply 96 by 0.75 (or divide by 4 and then multiply by 3). 
96 x 0.75 = 72. Therefore, the best choice is B: 72.

Question 4

Convert the percent to a decimal.&#10;1.6%&#10;A) 1.6&#10;B) 16.0&#10;C) 0.016&#10;D) 0.16

Accepted Answer

To convert a percent to a decimal, move the decimal point two places to the left. Therefore, 1.6% is equivalent to 0.016 as a decimal. To convert a percent to a decimal, we move the decimal point two places to the left. So for 1.6%, we get 0.016 as the decimal representation. Therefore, the correct choice is C.

Question 5

Solve the problem.&#10;A certain county charges 4% sales tax. Find the sales tax on a stereo that cost $890 and the total cost of the stereo, including tax. Round answers to the nearest cent.&#10;A) $26.70, $916.70&#10;B) $44.50, $934.50&#10;C) $356.00, $1246.00&#10;D) $35.60, $925.60

Accepted Answer

The sales tax is 4% of $890, which is $35.60. The total cost of the stereo, including tax, is $890 + $35.60 = $925.60.

Question 6

Perform the indicated operations.&#10;Divide 10.26 by 1.9.&#10;A) 6.4&#10;B) 54&#10;C) 0.54&#10;D) 5.4

Accepted Answer

Dividing 10.26 by 1.9 gives 5.4.

Question 7

Convert the percent to a decimal.&#10;2.9%&#10;A) 0.0029&#10;B) 2.9&#10;C) 0.029&#10;D) 0.29

Accepted Answer

To convert a percent to a decimal, divide by 100. So, 2.9% is equal to 0.029 in decimal form. Choice A is too small because it is equivalent to 0.29%, while choice B is too big because it is equivalent to 290%. To convert a percent to a decimal, move the decimal point two places to the left. Therefore, 2.9% becomes 0.029. The correct answer is C, 0.029.

Question 8

Round as indicated.&#10;Round 13.342 to tenths.&#10;A) 13.4&#10;B) 13.2&#10;C) 13.34&#10;D) 13.3

Accepted Answer

13.342 rounded to tenths would be 13.3 since the digit in the tenths place is 4, which is less than 5, so the digit in the tenths place remains 3. In order to round to tenths, we look at the digit in the tenths place (the second digit after the decimal point), which is 4. If this digit is 5 or greater, we round up; if it is less than 5, we round down. Since 4 is less than 5, we round 13.342 down to the nearest tenth, which is 13.3. Therefore, the answer is D.

Question 9

Convert the decimal to a percent.&#10;5.33&#10;A) 533%&#10;B) 53.3%&#10;C) 0.0533%&#10;D) 0.533%

Accepted Answer

To convert a decimal to a percent, you multiply the decimal by 100. Therefore, 5.33 * 100 = 533%.

Question 10

Convert the decimal to a percent.&#10;0.62&#10;A) 620%&#10;B) 6.2%&#10;C) 0.062%&#10;D) 62%

Accepted Answer

To convert a decimal to a percent, you move the decimal point two places to the right and add a percent sign. So, 0.62 as a percent is 62%. The other choices are incorrect because they either move the decimal point too many or too few places or add too many or too few percent signs. To convert a decimal to a percent, move the decimal point two places to the right and add a percent sign. So, 0.62 as a percent would be 62%.
