To find the percentage of shaded squares in the grid, you would divide the number of shaded squares (10) by the total number of squares (25) and then multiply by 100. So, 10 shaded squares out of 25 total squares is 10/25 = 0.4. Multiplying 0.4 by 100 gives you a percentage of 40%.

Go to the Ordnance Survey website (UK) and information on using a 6 figure grid reference can be found there. Basically, the UK is covered in 100,000 metre grid squares. Each grid square is identified by two letters. These squares are further divided into 10,000 metre squares that are numbered along the map's borders. An example reference could be: SD 638365 The SD identifies the 100,000 metre square, the 63 is the vertical line to the west of the point. The 8 is the tenths from that line easterly to the point. The 36 is the horizontal line south of the point. The 5 is tenths northerly from the line to the point. (5 would be half way). Instructions on taking grid references are printed on all Ordnance Survey Maps.
It is: 5/20 times 100 = 25% shaded squares

To find the percentage of shaded squares in the grid, you would divide the number of shaded squares (10) by the total number of squares (25) and then multiply by 100. So, 10 shaded squares out of 25 total squares is 10/25 = 0.4. Multiplying 0.4 by 100 gives you a percentage of 40%.
To model 1.04 on a grid, you can represent it as a square with side lengths of 1 and 0.04 units. This can be visualized as a square divided into 100 smaller squares, with 4 of those smaller squares shaded to represent the 0.04 part. Each smaller square would represent 0.01. This grid model can help demonstrate the concept of decimals and their relationship to whole numbers.

There are 5 squares in a 2 by 2 grid if the large square enclosing all four smaller squares is included in the count.
An 8 by 8 grid would have 64 squares(multiply 8 times 8 to get the square).
To represent 1.13-1.02 on a hundredths grid, you would first draw 1 whole square to represent the 1 before the decimal point. Next, you would divide the grid into 100 smaller squares to represent the hundredths. You would shade in 13 out of the 100 squares to represent the 0.13 part of 1.13. Then, you would subtract 1.02 by shading in 2 out of the 100 squares to represent the 0.02 part. The difference between the shaded squares for 1.13 and 1.02 would give you the visual representation of the subtraction on the hundredths grid.
You really should do your own homework - this is a question designed to make you analyse number patterns and devise a method to predict the answer that can be applied to grids of differing size. If we start with a square cut into a 3x3 grid, we can count the nine single (1x1) squares in the grid, the one 3x3 square, and then four 2x2* squares, making a total of 14. Try it out, then work your way up to 6x6 (a 36 square grid) by way of 4x4 and 5x5, looking to see how the grid's dimensions correlate to the number of varying-sized squares that can be counted. As a tip- in a 6x6 grid, you will have one 6x6 square, thirty-six 1x1 squares, and how many 2x2, 3x3, 4x4, and 5x5 squares? *The squares can overlap, obviously.
