In the number 4.391, what place is the 9 in?
- A.
Tenths
- B.
Ones
- C.
Thousandths
- D.
Hundredths
Correct Answer
D. HundredthsExplanation
The number 4.391 can be divided into different place values. The 9 in this number is in the hundredths place. The hundredths place is the third digit after the decimal point, counting from left to right. In this case, the 9 is in the third decimal place, representing hundredths.Rate this question:

Round 4.18 to the nearest TENTH
- A.
4.20
- B.
4.10
- C.
4.8
Correct Answer
A. 4.20Explanation
The correct answer is 4.20 because when rounding to the nearest tenth, we look at the digit in the hundredth place (the second decimal place). If the digit is 5 or greater, we round up, and if it is less than 5, we round down. In this case, the digit in the hundredth place is 0, which is less than 5. Therefore, we round down to the nearest tenth, which is 4.2.Rate this question:

What is the expanded form of: 82.64
- A.
800 + 20 + .06 + .004
- B.
80 + 2 + .6 + .04
- C.
8 + 2 + .6 + .004
Correct Answer
B. 80 + 2 + .6 + .04Explanation
The expanded form of 82.64 is 80 + 2 + .6 + .04. This is because 82.64 can be broken down into 80 (representing the 80s place), 2 (representing the 2s place), .6 (representing the tenths place), and .04 (representing the hundredths place).Rate this question:

What is the expanded form of: 13.274
- A.
(3 x 10) + (2 x .1) + (7 x .1) + (4 x .001)
- B.
(3 x 1) + (2 x 10) + (4 x .1) + (7 x .001)
- C.
(1 x 10) + (3 x 1) + (2 x .1) + (7 x .01) + (4 x .001)
Correct Answer
C. (1 x 10) + (3 x 1) + (2 x .1) + (7 x .01) + (4 x .001)Explanation
The correct answer is the expanded form of the number 13.274, which is (1 x 10) + (3 x 1) + (2 x .1) + (7 x .01) + (4 x .001). This means that the number can be expressed as the sum of its place values, where 10 represents the tens place, 1 represents the ones place, .1 represents the tenths place, .01 represents the hundredths place, and .001 represents the thousandths place.Rate this question:

What does this hundredths grid represent?
- A.
0.33
- B.
0.28
- C.
0.08
Correct Answer
B. 0.28Explanation
The hundredths grid represents the decimal value 0.28. This is because the grid is divided into 100 equal parts, and the shaded portion represents 28 out of those 100 parts. Therefore, the decimal value of the shaded portion is 0.28.Rate this question:

Which ordered pair is represented by point X?
- A.
(4, 2)
- B.
(1, 5)
- C.
(2, 4)
Correct Answer
A. (4, 2)Explanation
Point X is represented by the ordered pair (4, 2) because the coordinates of X match with the first set of coordinates given. The first number in the ordered pair represents the x-coordinate, which is 4 in this case, and the second number represents the y-coordinate, which is 2 in this case. Therefore, (4, 2) is the correct answer.Rate this question:

Which ordered pair is represented by point Z?
- A.
(3, 2)
- B.
(1, 5)
- C.
(2, 4)
Correct Answer
C. (2, 4)Explanation
The ordered pair (2, 4) is represented by point Z because the x-coordinate is 2 and the y-coordinate is 4. This matches the location of point Z on the graph.Rate this question:

Round 6.184 to the nearest WHOLE
- A.
7.1
- B.
7
- C.
6
Correct Answer
C. 6Explanation
The given number, 6.184, needs to be rounded to the nearest whole number. When rounding to the nearest whole number, we look at the decimal part. If the decimal part is 0.5 or greater, we round up to the next whole number. If the decimal part is less than 0.5, we round down to the current whole number. In this case, the decimal part of 6.184 is less than 0.5, so we round down to the current whole number, which is 6.Rate this question:

Solve this problem: (Use a piece of paper to line up decimals and subtract) 65.22 - 4.715 = ?
- A.
60.505
- B.
62.350
- C.
61.402
Correct Answer
A. 60.505Explanation
To solve the problem, we need to subtract 4.715 from 65.22. When we line up the decimals, we subtract 5 from 2, which requires borrowing from the tens place. This gives us 12 - 5 = 7 in the tenths place. Then, we subtract 1 from 6, which gives us 5 in the ones place. Finally, we subtract 4 from 6, which gives us 2 in the tens place. Therefore, the correct answer is 60.505.Rate this question:
