Question 1

A bakery sells cookies in packages of 8. A school is planning a party for 126 students. If each student is to receive one cookie, what is the minimum number of packages the school needs to buy?

Accepted Answer

16

Answer

To solve this, you need to divide the total number of students (126) by the number of cookies in each package (8). 126 ÷ 8 = 15.75. Since the school cannot buy a fraction of a package, they must round up to the next whole number to ensure every student gets a cookie. Therefore, they need to purchase 16 packages.

Question 2

Which of the following fractions is equivalent to 0.65?

Accepted Answer

13/20

Answer

The decimal 0.65 can be written as the fraction 65/100. To find an equivalent fraction, you simplify 65/100 by dividing both the numerator and the denominator by their greatest common factor, which is 5. 65 ÷ 5 = 13, and 100 ÷ 5 = 20. So, the equivalent fraction is 13/20.

Question 3

A submarine is located at a depth of -250 feet. It then ascends 85 feet. What is the submarine's new position relative to sea level?

Accepted Answer

-165 feet

Answer

The initial position is -250 feet. Ascending means moving up, which is represented by adding a positive number. The calculation is -250 + 85. When adding a positive number to a negative number, you find the difference between their absolute values (250 - 85 = 165) and keep the sign of the number with the larger absolute value, which is negative. Therefore, the new position is -165 feet.

Question 4

What is the result of 42.5 x 10^3?

Accepted Answer

42,500

Answer

Multiplying a decimal by a power of 10, such as 10^3 (which is 1,000), involves moving the decimal point to the right. The exponent '3' indicates that the decimal point should be moved 3 places to the right. For 42.5, moving the decimal three places gives 42,500.

Question 5

A recipe for a batch of muffins requires 3/4 cup of sugar. If you want to make only 1/2 of a batch, how much sugar will you need?

Accepted Answer

3/8 cup

Answer

To find the amount of sugar for half a batch, you need to multiply the original amount of sugar by 1/2. The calculation is (3/4) * (1/2). To multiply fractions, you multiply the numerators together (3 * 1 = 3) and the denominators together (4 * 2 = 8). The result is 3/8 cup of sugar.
