Each shaded area in the grids below represents a decimal.

Question

which explains how to find the sun of the decimals?

Count 40 shaded squares, or 0.40, on the first grid and 80 shaded squares, or 0.80, on the second grid. Then add them together to get 1.20.

Count 44 shaded squares, or 0.44, on the first grid and 87 shaded squares, or 0.87, on the second grid. Then add them together to get 1.31.

Count 56 shaded squares, or 0.56, on the first grid and 13 shaded squares, or 0.13, on the second grid. Then add them together to get 0.69.

Count a total of 100 squares, or 1.00, on the left grid and 100 squares, or 1.00, on the right grid. Then add them together to get 2.00.

Answer 1

To find the sum of the decimals represented by the shaded areas in the grids, you can follow these steps:

1. Count the Shaded Squares: For each grid, count the number of shaded squares.

2. Convert to Decimal:

   • For the first grid, take the number of shaded squares, divide it by 100 (assuming each grid has a total of 100 squares), and record the resulting decimal.
   • For example, if there are 40 shaded squares, it converts to 0.40 (40 divided by 100).

3. Repeat for the Second Grid: Do the same for the second grid, counting and converting to a decimal.

   • For example, if there are 80 shaded squares on the second grid, it converts to 0.80.

4. Add the Decimals: Add the two decimal values together to find the sum:

   • For example, \(0.40 + 0.80 = 1.20\).

5. Example Calculations:

   • If you count 44 shaded squares on the first grid (0.44) and 87 on the second grid (0.87), then \(0.44 + 0.87 = 1.31\).
   • If you count 56 on the first grid (0.56) and 13 on the second grid (0.13), then \(0.56 + 0.13 = 0.69\).
   • If both grids have all squares shaded (100 each), then \(1.00 + 1.00 = 2.00\).

By systematically counting the shaded areas, converting to decimals, and then adding those decimals together, you can effectively find the total amount represented by the shaded areas in the grids.
