Multiply 4 by −5/8. Write the answer as a mixed number in simplest form.(1 point)
To multiply 4 by -5/8, we multiply the numerators (4 * -5) to get -20, and multiply the denominators (1 * 8) to get 8. Therefore, the result is -20/8.
To simplify this mixed number, we divide the numerator (20) by the denominator (8) to get 2 with a remainder of 4. So the mixed number is -2 and 4/8.
Simplifying the fraction further, we can reduce 4/8 by dividing both the numerator and denominator by their greatest common factor, which is 4. This gives us 1/2. Therefore, the answer as a mixed number in simplest form is:
-2 and 1/2

Multiply −2 1/2 by −1 3/5. Write the answer as a decimal
To multiply -2 1/2 by -1 3/5, we first need to convert the mixed numbers into improper fractions.
-2 1/2 can be written as -5/2.
-1 3/5 can be written as -8/5.
To multiply these fractions, we multiply the numerators (-5 * -8) to get 40 and multiply the denominators (2 * 5) to get 10.
Therefore, the result is 40/10.
Simplifying the fraction, we divide the numerator (40) by the denominator (10) to get 4.
Therefore, the answer as a decimal is 4.
-2 1/2 can be written as -5/2.

To find the total area of Oak Manor, we multiply the length and width of the town:
3.8 miles * 4.2 miles = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 square miles.
3.8 miles * 4.2 miles = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 square miles.

To find the diver's elevation when he is 23% of the way down, we multiply the depth of the treasure by 23%.
97.2 ft * 0.23 = 22.356 ft
Therefore, the diver's elevation when he is 23% of the way down is a depth of 22.356 ft below the surface.
However, the options provided do not match this calculation exactly. The closest option is -32.4 ft.
97.2 ft * 0.23 = 22.356 ft
Therefore, the diver's elevation when he is 23% of the way down is a depth of 22.356 ft below the surface.
However, the options provided do not match this calculation exactly. The closest option is -32.4 ft.

If the basketball player is 623 feet tall and his infant son is 1/4 as tall, we can find the son's height by multiplying the player's height by 1/4.
623 feet * (1/4) = 155.75 feet
Therefore, the son's height is 155.75 feet. However, none of the options provided match this calculation exactly. The closest option is 123 ft.
623 feet * (1/4) = 155.75 feet

If the basketball player is 6 2/3 feet tall and his infant son is 1/4 as tall, we can find the son's height by multiplying the player's height by 1/4.
6 2/3 feet can be written as (6 + 2/3) feet, which is equivalent to (18/3 + 2/3) feet, or 20/3 feet.
To find the son's height, we multiply (20/3) feet by (1/4):
(20/3) feet * (1/4) = 20/12 feet = 5/3 feet
Therefore, the son's height is 5/3 feet, which can also be written as 1 2/3 feet. None of the options provided match this exact calculation.
