• C.

26.88

• D.

0.2688

C. 26.88
Explanation
The correct answer is 26.88. To find the product of 33.6 and 0.8, we multiply the two numbers together. When we multiply 33.6 by 0.8, we move the decimal point one place to the left in 33.6 to get 3.36, and then multiply by 8 to get 26.88. Therefore, the answer is 26.88.

### What is the average of 106, 109, 98 and 111?

• A.

423

• B.

110

• C.

106

• D.

100

C. 106
Explanation
The average of a set of numbers is found by adding all the numbers together and then dividing the sum by the total number of numbers. In this case, the sum of 106, 109, 98, and 111 is 424. Dividing 424 by 4 (the total number of numbers) gives us an average of 106.

### What number divided by 18 is equal to 2/3?

• A.

12

• B.

6

• C.

18

• D.

9

A. 12
Explanation
To find the number that divided by 18 is equal to 2/3, we can set up the equation: x/18 = 2/3. To solve for x, we can cross multiply: 3x = 36. Dividing both sides by 3 gives us x = 12. Therefore, 12 divided by 18 is equal to 2/3.

### What is 0.186 rounded to the nearest tenth?

• A.

0.19

• B.

0.1

• C.

0.2

• D.

0.18

C. 0.2
Explanation
0.186 rounded to the nearest tenth is 0.2. When rounding to the nearest tenth, we look at the digit in the hundredth place, which is 8 in this case. Since 8 is greater than or equal to 5, we round up the digit in the tenth place, which is 1, to the next higher number, which is 2. Therefore, the rounded number is 0.2.

### What is the simplest form of the fraction 9/45?

• A.

4-Jan

• B.

15-Mar

• C.

5-Jan

• D.

6-Jan

C. 5-Jan
Explanation
The simplest form of a fraction is when the numerator and denominator have no common factors other than 1. In this case, both 9 and 45 can be divided by 9, resulting in the fraction 1/5. Therefore, the simplest form of 9/45 is 1/5.

### What is \$7.48 rounded to the nearest dollar?

• A.

7.4

• B.

7.5

• C.

7

• D.

8

C. 7
Explanation
When rounding a number to the nearest dollar, we look at the decimal place immediately to the right of the dollar amount. In this case, the decimal place is 4. Since 4 is less than 5, we round down to the nearest dollar. Therefore, \$7.48 rounded to the nearest dollar is \$7.

• B.

14

• C.

13

• D.

12

A. 12.3
Explanation
The best estimate for 4.8 + 7.46 is 12.3 because when we round 4.8 to the nearest whole number, it becomes 5. Adding 5 to 7.46 gives us 12.46. Rounding 12.46 to the nearest tenth, we get 12.3.

The numbers in the hundreds, tens, and ones places do not affect the comparison since the thousands place has the highest weightage.

### Which denominator is needed to make (3/x) equal to 9/12?

• A.

5

• B.

9

• C.

3

• D.

4

D. 4
Explanation
To make (3/x) equal to 9/12, we need to find the value of x. We can do this by setting up a proportion. Cross-multiplying, we get 3 * 12 = 9 * x, which simplifies to 36 = 9x. Dividing both sides by 9, we find that x = 4. Therefore, the denominator needed to make (3/x) equal to 9/12 is 4.
