The product of 4/7 and -20/2 is -937.
To find the product of 4/7 and -20/2, you simply multiply the numerators and denominators:
(4/7) * (-20/2) = (4 * -20) / (7 * 2)
The numerator becomes -80 and the denominator becomes 14. Therefore, the product is -80/14.
However, this fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2:
-80/14 = -40/7.
So, the simplified product of 4/7 and -20/2 is -40/7.
To find the product of 4/7 and -20/2, we need to multiply the numerators (top numbers) together and multiply the denominators (bottom numbers) together.
The numerator for the product is (4 * -20) = -80, and the denominator is (7 * 2) = 14.
So, the product of 4/7 and -20/2 is -80/14.
Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2.
Dividing -80 by 2 gives -40, and dividing 14 by 2 gives 7.
Therefore, the simplified product of 4/7 and -20/2 is -40/7.
So, the correct answer is: negative 40/7.
The elevation of the basement floor in a building is -15 ft. The elevation of the roof is 37 feet. What is the distance from the basement floor to the roof?(1 point)

The distance from the basement floor to the roof can be found by taking the difference between their elevations.
37 ft (elevation of the roof) minus (-15 ft) (elevation of the basement floor) is equal to 37 ft + 15 ft = 52 ft.
Therefore, the distance from the basement floor to the roof is 52 feet.

To find the product of 4/7 and -20/2, we can multiply the numerators and the denominators.
Numerator: 4 * -20 = -80
Denominator: 7 * 2 = 14
So the product is -80/14.
This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
Numerator: -80 ÷ 2 = -40
Denominator: 14 ÷ 2 = 7
Thus, the simplified product is -40/7.
Therefore, the answer is A. -2/35 (negative 2 over 35).
