Place Value Exercise: Building the Number 40 Using Ones and Tens

To solve this problem, we need to represent the number 40 using tens and ones.

Step 1: Determine how many tens are in 40. Since one ten equals 10, dividing 40 by 10 gives us:

• $\frac{40}{10} = 4$. Therefore, there are 4 tens in 40.

Step 2: Determine how many ones (units) are needed. With 40 being evenly divided by 10, there are no ones required, or 0 ones:

• Remainder of $\frac{40}{10}$ is 0.

Hence, the number 40 can be represented by 4 tens and 0 ones.

Therefore, the correct choice is:
- 4 boxes of tens plus 0 boxes of ones.

Therefore, the solution to the problem is $40 = 4 \text{ tens} + 0 \text{ ones}$, which looks like this:
