Question

Type the correct answer in each box. Use numerals instead of wordsFind the value of each decimal model and then find the sum

Answer 1

To find the decimal values you have to count the number of shaded squares and divide it by the total number of squares in the grid.

Left value:

The grid is 10 x 10, which means that it is divided into 100 squares.

There are 23 shaded squares in the grid, so you can determine the decimal value as follows:

`\frac{nº\text{shaded squares}}{total\text{ number of squares}}=(23)/(100)=0.23`

Right value:

The grid is 10 x 10, so it is divided into 100 squares.

The number of shaded squares is 62. Divide 62 by 100 to determine the decimal value:

`\frac{nº\text{shaded squares}}{total\text{ number of sqaures}}=(62)/(100)=0.62`

Now what is left to do is to add both decimal values:

`0.23+0.62=0.85`
