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

Build the number 40 from units 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:
