how many blocks do you shade in a 10 by 10 grid to represent 1/20

Answer 1

To represent 1/20 on a 10 by 10 grid, you need to shade in 1/20th of the total blocks.

The total number of blocks in a 10 by 10 grid is 10 x 10 = 100 blocks.

To find 1/20th of 100 blocks, you divide 100 by 20:
100 / 20 = 5 blocks.

Therefore, you need to shade in 5 blocks to represent 1/20 on a 10 by 10 grid.
