Question

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms. About how many times more mass does a giraffe have than an ant?

Answer 1

5973 because there's 6000 grams in 6 kilograms and there's 27 grams in an ant and 6000 minus 27 is 5973 or 59.73 kilograms more

Answer 2

Given that average mass of an ant
`= 3 * 10^(-3)` grams.

Given that average mass of a giraffe
`= 2 * 10^(3)` Kilograms.

Now we have to find about how many times more mass does a giraffe have than an ant. Before carring out any comparision, we must make both units equal.

Like convert kilogram into gram or gram into kilogram.

I'm going to convert kilogram into gram using formula

1 Kg = 1000 g

So the average mass of a giraffe
`= 2 * 10^(3) *10^3`grams.

Now we just need to divide mass of giraffe by mass of ant to find the answer.

`(2 * 10^(3) *10^3 )/(3 * 10^(-3) )`

`= (2 * 10^(3) *10^3 *10^(3))/(3 )`

`= (2 * 10^(3+3+3))/(3 )`

`= (2 * 10^9)/(3 )`

`= (2)/(3 ) * 10^9`

=666666666.667

Hence final answer is
`(2)/(3 ) * 10^9` which is approx 666666666.667.
