Question

The number 28.5 is 300 times greater than which number?

Answer 1

To answer this question, we can rewrite the question as follows:

$28.5=300\cdot x$

To solve for x, we need to divide both sides of the equation by 300. Then, we have:

$\frac{28.5}{300}=\frac{300}{300}\cdot x\Rightarrow x=\frac{28.5}{300}\Rightarrow x=0.095$

Therefore, if we divide 28.5 by 0.095, we have:

$\frac{28.5}{0.095}=300$

That is 28.5 is 300 times greater than 0.095.

In summary, the number 28.5 is 300 times greater than 0.095 - the answer is 0.095 (option b).

[This is the same case to say, for example, the number 10 is 2 times greater than which number. We can proceed identically, and we can write:

$10=2\cdot x\Rightarrow x=\frac{10}{2}\Rightarrow x=5$

That is 10 is 2 times greater than 5:

$\frac{10}{5}=2$
