Question

Of the 81 astronauts in the space program, 43 are in outer space. What is the ratio of the number of astronauts on Earth to the total number of astronauts?

Answer 1

Answer:

Ratio = 0.4691

Step-by-step explanation:

If we have a total of 81 astronauts, and 43 of them are in outer space, the number of astronauts on Earth is 81 - 43 = 38 astronauts

The ratio of the number of astronauts on Earth to the total number of astronauts can be calculated just dividing the two values: in the numerator, the number of astronauts on Earth, and in the denominator, the total number of astronauts. So:

Ratio = 38 / 81 = 0.4691

Answer 2

Answer:

38:81

Step-by-step explanation:

There are a total of 81 Astronauts in the space program.

Out of these, 43 are in outer space.

We are to determine the ratio of the number of astronauts on Earth to the total number of astronauts.

Number of Astronauts on Earth = Total Number - Number in Outer Space

                                                =81-43 = 38

Therefore:

Number of astronauts on Earth : The total number of astronauts. = 38:81
