Answer 2

To solve the given equation, let's convert the numbers from base-10 (decimal) to base-2 (binary).

2 (decimal) is equivalent to 10 (binary). 8 (decimal) is equivalent to 1000 (binary).

Now, let's perform the addition:

10 (binary)

• 1000 (binary)

---

1010 (binary)

The result of 10 (decimal) in binary is 1010.

To convert this binary number to base-10, we can use the positional notation:

1 * 2^3 + 0 * 2^2 + 1 * 2^1 + 0 * 2^0 = 8 + 0 + 2 + 0 = 10 (decimal).

Therefore, 10 (decimal) in base-10 is equal to 1010 in binary.

Now, let's find the number of hundreds in 10 (decimal):

Since 10 is less than 100, it does not have any hundreds. So 10 (decimal) has 0 hundreds.

In conclusion, 10 (decimal) in base-10 does not have any hundreds.
