### Oder the following numbers in descending order: 0.02, 0.22, 0.2

• A.

0.22 , 0.2,  0.02

• B.

0.02, 0.22, 0.2

• C.

0.2, 0.22, 0.02

A. 0.22 , 0.2,  0.02
Explanation
The correct answer is 0.22, 0.2, 0.02. This is because when ordering numbers in descending order, we arrange them from largest to smallest. In this case, 0.22 is the largest number, followed by 0.2, and finally 0.02, which is the smallest number.

### What percentage of fruits in the box are MANGOES, if there are 30 oranges and 20 mangoes in the box?

• A.

25%

• B.

50%

• C.

40%

• D.

35%

C. 40%
Explanation
The percentage of mangoes in the box can be calculated by dividing the number of mangoes by the total number of fruits and then multiplying by 100. In this case, there are 20 mangoes and the total number of fruits is 30 + 20 = 50. So, the percentage of mangoes is (20/50) * 100 = 40%.

### Write in figures the number: One million, ten thousand and sixty-nine.

• A.

1,100,069

• B.

1,169,000

• C.

1,000,169

• D.

1,010,069

D. 1,010,069
Explanation
The given figure "1,010,069" represents the number "One million, ten thousand and sixty-nine". The first digit "1" represents one million, followed by three zeros to indicate the thousands place. Then, "10" represents ten thousand, and "69" represents sixty-nine. Therefore, the figure "1,010,069" accurately represents the given number.

### Every 10th spectator at a sports meeting is admitted free. How many spectators are admitted free if 248 spectators come to the sports meeting?

• A.

22

• B.

23

• C.

24

• D.

25

C. 24
Explanation
Every 10th spectator is admitted free, so we need to find the number of multiples of 10 that are less than or equal to 248. By dividing 248 by 10, we get 24 with a remainder of 8. This means that there are 24 groups of 10 spectators, so 24 spectators are admitted free.

Explanation
The total weight of both bags can be found by adding the weight of the first bag (2.5kg) to the weight of the second bag (3.75kg). Therefore, the total weight of both bags is 6.25kg.

### A cube has a side of 6cm. Calculate the volume of the cube.

• A.

18cm3

• B.

216cm3

• C.

18cm

• D.

216cm

B. 216cm3
Explanation
The volume of a cube is calculated by multiplying the length of one side by itself three times. In this case, the length of one side is given as 6cm. So, 6cm x 6cm x 6cm equals 216cm3.

### Cato runs the 100 meters in 9.9 seconds and Sean runs the same race in 9.98 seconds. Who is the faster runner?

• A.

Cato

• B.

Sean

A. Cato
Explanation
Cato is the faster runner because he completes the 100 meters in a shorter amount of time compared to Sean. Cato takes 9.9 seconds to finish the race, while Sean takes 9.98 seconds. Therefore, Cato has a faster running time and can be considered the quicker runner.

### Roshan has \$2.40 and Chung has 20 cents more than Roshan. How much money do they have altogether?

• A.

\$4.00

• B.

\$4.80

• C.

\$5.00

• D.

\$5.80

C. \$5.00
Explanation
Roshan has \$2.40 and Chung has 20 cents more than Roshan. To find out how much money they have altogether, we need to add their amounts. If Roshan has \$2.40, Chung would have \$2.40 + \$0.20 = \$2.60. Adding these amounts together, we get \$2.40 + \$2.60 = \$5.00. Therefore, they have \$5.00 altogether.

C. Option 3
Explanation
The table above is showing the frequencies of different drinks. In the "TALLY" column, each "I" represents one occurrence of the drink. In the "FREQUENCY" column, the number indicates the total count of occurrences for each drink. Based on the table, the correct answer is Option 3 because it accurately reflects the frequency of water, which is 8.

2/6

• B.

1/6

• C.

3/4

• D.

2/4

C. 3/4
Explanation
The given expression is 1/4 + 1/2. To add these fractions, we need to find a common denominator, which in this case is 4. We can rewrite 1/2 as 2/4. Now, we can add the fractions: 1/4 + 2/4 = 3/4. Therefore, the correct answer is 3/4.

### Evan wants to measure the length of his room. Which unit of measure is appropriate to measure the length of his room?

• A.

Centimeter

• B.

Foot

• C.

Inch

• D.

Milimeter

A. Centimeter
Explanation
Centimeter is the appropriate unit of measure to measure the length of Evan's room. Centimeters are commonly used for measuring smaller distances, such as the length of a room. Feet and inches are more commonly used for measuring longer distances, such as height or distance. Millimeters are even smaller units of measure and may not be practical for measuring the length of a room.

• A.

1/3

• B.

1/2

• C.

12 sheets

• B.

231 sheets

• C.

273 sheets

• D.

A. 12 sheets
Explanation
To find the number of sheets of paper in each study guide, we divide the total number of sheets used by the number of students. In this case, Mrs. Perkins used 252 sheets of paper for 21 students. Therefore, each study guide contains 12 sheets of paper.

### Use the rectangle below to answer the question. x is 5 meters and y is 17 meters.  What is the area of the rectangle?

• A.

12 square meters

• B.

22 square meters

• C.

44 square meters

• D.

85 square meters

D. 85 square meters
Explanation
The area of a rectangle is calculated by multiplying its length by its width. In this case, the length (y) is given as 17 meters and the width (x) is given as 5 meters. Therefore, the area of the rectangle is 17 meters multiplied by 5 meters, which equals 85 square meters.

### What is 92.53 ÷ 10?

• A.

0.9253

• B.

9.253

• C.

92.53

• D.

925.3

B. 9.253
Explanation
When dividing 92.53 by 10, we move the decimal point one place to the left. This is because dividing by 10 is equivalent to dividing by a power of 10, which means shifting the decimal point to the left. Therefore, the correct answer is 9.253.

### What is the value of w in the equation 116 -  w = 95?

• A.

W = 19

• B.

W = 21

• C.

W = 210

• D.

W = 211

B. W = 21
Explanation
To find the value of w in the equation 116 - w = 95, we need to isolate w on one side of the equation. By subtracting 116 from both sides, we get -w = -21. To solve for w, we multiply both sides by -1, which gives us w = 21.
