25. The Great Pyramids weigh 6x10^9 kilograms. The Space Shuttle weighs 2x10^6 kilograms. How many times heavier are the Pyramids than the Space Shuttle?
A.The Pyramids are 3 times heavier than the space shuttle.
B.The pyramids are 30 times heavier than the Space shuttle.
C.The pyramids are 300 times heavier than the Space Shuttle.
D.The pyramids are 3000 times heavier than the Space shuttle.
What I did was 6x10^9/2x10^6 which equals 4x10^3. But my answer didn't match the choices.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
(6*10^9)/(2*10^6) = 3*10^3
6/2 = 3
To compare the weights of the Pyramids and the Space Shuttle, you correctly calculated the ratio by dividing the weight of the Pyramids by the weight of the Space Shuttle: (6x10^9 kilograms) / (2x10^6 kilograms) = 3x10^3.
However, in order to choose the closest value from the given choices, you need to simplify the result. 3x10^3 can be written as 3000, so the correct answer is D. The Pyramids are 3000 times heavier than the Space Shuttle.
