A) 2,070,015
B) 2,070,150
C) 2,700,015
D) 2,700,150

Accepted Answer

The number "two million seven hundred thousand fifteen" can be written as 2,700,015. Therefore, the best choice is C.

Question 5

Which is the product of $31 × 101?
A) $1,313
B) $3,100
C) $3,131
D) $3,441

Accepted Answer

To multiply two-digit numbers, we can use the distributive property. $31$ can be written as $30+1$ and then distribute over $101$ to get: $31	imes101=(30+1)	imes101=30	imes101+1	imes101=3030+101=3131$.

Question 6

Which is the total cost of 3.5 pounds of grapes at $2.10 a pound?
A) $5.60
B) $6.35
C) $7.04
D) $7.35

Accepted Answer

The total cost of 3.5 pounds of grapes at $2.10 a pound is calculated by multiplying the price per pound by the number of pounds: 3.5 pounds * $2.10/pound = $7.35.

Question 7

Ryan bought a phone with an original price of $145.80. He received a 25% discount off the phone, which amounted to $36.45. How much did he pay for the phone?
A) $109.35
B) $119.45
C) $171.25
D) $182.25

Accepted Answer

To find out how much Ryan paid for the phone, we need to subtract the discount amount from the original price:

$145.80 - $36.45 = $109.35

Therefore, Ryan paid $109.35 for the phone after the discount.

Question 8

When Sarah bought school supplies, the total cost was $31.76. Sarah gave the cashier two twenty-dollar bills, so her change should be $8.24.

Accepted Answer

The amount Sarah gave to the cashier is: 
$20 + $20 = $40 
To find Sarah's change, we need to subtract the total cost of the school supplies from the amount she gave: 
$40 - $31.76 = $8.24 
Therefore, the answer is true.

Question 10

Which is the best estimate to find the quotient for 1,380 $\div$ 115?
A) 1,400 $\div$ 120
B) 1,400 $\div$ 100
C) 1,300 $\div$ 150
D) 1,300 $\div$ 100

Accepted Answer

The best estimate would be to round both numbers to the nearest hundred. 1,380 rounds to 1,400 and 115 rounds to 100. Therefore, the best estimate would be 1,400 ÷ 100 = 14. Option B is the only choice with 1,400 ÷ 100, making it the best estimate.

Question 11

Which is the product of 419 × 823?
A) 344,837
B) 346,932
C) 348,608
D) 404,093

Accepted Answer

The answer of Which is the product of 419 ×...

Question 12

Juan wants to place a border along his four flower gardens. He measures the lengths of each and finds them to be 1.25 m, 1.4 m, 0.83 m, and 1.68 m. If Juan buys 5 meters of border, he will have just enough border to line the front of the four gardens.

Accepted Answer

The total length of the borders needed for the four gardens is 1.25 m + 1.4 m + 0.83 m + 1.68 m = 5.16 m, which is more than 5 meters.

Question 13

Which describes the value of the underlined digit? $16.10\underline1$
A) 1 ten-thousandth
B) 1 thousandth
C) 1 hundredth
D) 1 tenth

Accepted Answer

The underlined digit is in the thousandths place, which means it represents 1 thousandth.

Question 14

Which is the quotient of 8,084 $\div$ 94?
A) 66
B) 76
C) 86
D) 96

Accepted Answer

To find the quotient of 8,084 divided by 94, you can use long division or a calculator. The correct calculation is 8,084 ÷ 94 = 86.

Question 15

Which describes the value of the underlined digit? $8.0\underline27$
A) 2 hundreds
B) 2 tens
C) 2 tenths
D) 2 hundredths

Accepted Answer

The digit underlined is in the hundredths place, so its value is 2 hundredths.

Question 16

What is the sum of 513.78 + 4.203?
A) 509.77
B) 517.983
C) 518.81
D) 5,179.83

Accepted Answer

To find the sum, we need to add the decimals in each place value. Starting from the right, 3 + 8 = 11 (write down 1 and carry over 1), 7 + 0 + 3 = 10 (write down 0 and carry over 1), 1 + 2 + 4 = 7, 5 + 0 = 5. So the sum is 517.983. Therefore, the best choice is B.

Question 17

Which is the quotient of 10.276 $\div$ 2.8?
A) 367
B) 36.7
C) 3.67
D) 0.367

Accepted Answer

To divide two decimals, we need to move the decimal point of the divisor (2.8) to the right until it becomes a whole number. Remember that whatever we do to the divisor, we also need to do to the dividend (10.276).

Therefore, we can move the decimal point of 2.8 one place to the right to get 28. We also need to move the decimal point of 10.276 one place to the right to get 102.76.

Now we can perform the division:

102.76 ÷ 28 = 3.67

Therefore, the answer is C.

Question 19

Mrs. Washington went to the store to purchase white boards for her students. The boards she chose cost $7.98 each. Her school has authorized up to $225, therefore, Mrs. Washington can purchase 29 boards.

Accepted Answer

To find out how many boards Mrs. Washington can purchase, we need to divide the authorized amount of $225 by the cost per board of $7.98:

$225 ÷ $7.98 ≈ 28.14

This means that Mrs. Washington can only purchase 28 boards, not 29.
