To represent the decimal 2.83 using grids, we can break down the components of the number:
- The "2" in 2.83 represents 2 whole units.
- The "0.83" represents 83 hundredths, which can be interpreted as 83% of a whole unit.
If we use a ten by ten grid (which represents one whole unit) to visualize this:
1. **Whole Units**:
- Two ten by ten grids filled in represent the two whole units (2).
2. **Hundredths**:
- For the decimal part, 0.83 means filling in 83 out of 100 smaller squares. This is represented by filling in 8 complete rows (each row has 10 squares, adding up to 80 squares) and 3 additional squares in the next row to make 83 squares filled.
Considering these components together, the correct representation of 2.83 using grids would be:
- Two ten by ten grid squares filled in (for the 2 whole units).
- Eight complete columns filled in (for the 80 squares) and three individual squares filled in (for the additional 3 squares).
Thus, the correct choice is:
**Two ten by ten grid squares filled in, eight columns of ten squares filled in and three individual squares filled in.**
