They are not equivalent, try adding in numerical values for x, both do not come out the same.

The average mass of an ant is approximately 3 × 10 − 3 grams. The average mass of a giraffe is approximately 2 × 10 3 kilograms.

Vika [28.1K]

Given that average mass of an ant $= 3 \times 10^{-3}$ grams.

Given that average mass of a giraffe $= 2 \times 10^{3}$ 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 $= 2 \times 10^{3} *10^3$ grams.

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

$\frac{2 \times 10^{3} *10^3 }{3 \times 10^{-3} }$

$= \frac{2 \times 10^{3} *10^3 *10^{3}}{3 }$

$= \frac{2 \times 10^{3+3+3}}{3 }$

$= \frac{2 \times 10^9}{3 }$

$= \frac{2}{3 } \times 10^9$

=666666666.667

Hence final answer is $\frac{2}{3 } \times 10^9$ which is approx 666666666.667.

Explain how u can find 3×584 using expanded form

stepladder [879]

You can solve it as 3*500+3*80+3*4. It the same as solving it normally, since you're essentially solving it as above (one place value at a time).
