How can you represent the number 100 using tens and ones?

Answer explanation

You can represent 100 as 10 tens and 0 ones, since 10 tens equal 100 (10 × 10 = 100) and there are no additional ones left over. Alternatively, you could think of it as 100 ones, because 100 × 1 = 100, though this is less common when focusing on tens and ones specifically.

If you have 3 hundreds, 4 tens, and 2 ones, what number do you have? How would you write it in expanded form?

Answer explanation

The number is 342, calculated as:

• 3 hundreds = 300

• 4 tens = 40

• 2 ones = 2
  Total: 300 + 40 + 2 = 342.
  In expanded form, it’s written as 300 + 40 + 2.
