Question

821 is how many times greater than 8, ., 2, 18.21?8, ., 2, 18.21 is what fractional part of 821821?

Answer 1

To determine how many times greater 821 is than 8, we can perform the calculation:

\[
\frac{821}{8} = 102.625
\]

So, 821 is 102.625 times greater than 8.

Next, let's look at how to express the number 2 and 18.21 in relation to 821. Since you provided 8, 2, and 18.21 without clear separation, I assume you are interested in the number 2.

To find how many times greater 821 is than 2:

\[
\frac{821}{2} = 410.5
\]

So, 821 is 410.5 times greater than 2.

Now, let's calculate how many times greater 821 is than 18.21:

\[
\frac{821}{18.21} \approx 45.1
\]

So, 821 is approximately 45.1 times greater than 18.21.

Next, we need to find what fractional part 2 (considering just the number 2) is of 821:

\[
\frac{2}{821}
\]

This value is approximately:

\[
\frac{2}{821} \approx 0.00243
\]

So as a fraction, it stays as \(\frac{2}{821}\).

If we assess the original question, we find:

- 821 is approximately **102.625** times greater than **8**.
- 821 is **410.5** times greater than **2**.
- 821 is approximately **45.1** times greater than **18.21**.

As a fractional part of 821, **2 is \(\frac{2}{821}\)**.
