Place Value Practice: Building the Number 27 with Tens and Units

To build the number 27 using units and tens, follow these steps:

• Step 1: Determine the number of tens in 27. Since 27 divided by 10 equals 2 with a remainder, we have 2 tens (20).

• Step 2: Determine the number of units (ones) in 27. The remainder when dividing 27 by 10 is 7. Thus, we have 7 units.

• Step 3: Verify this. 2 tens amount to 20, and adding 7 units gives us 27. Therefore, this configuration is correct.

The graphical representation that shows 2 sets of ten blocks and 7 unit blocks correctly illustrates the number 27.

Therefore, the solution to the problem is illustrated by the fourth choice, which shows 2 groups of tens and 7 individual units.
