Answer 2

Calculation of White and Black Pieces

To determine the proportion of white and black pieces on a chessboard, we need to know the total number of pieces and the number of black pieces.

According to the given information, there are 14 pieces on the chessboard, with 5 of them being black.

To calculate the proportion of white pieces, we subtract the number of black pieces from the total number of pieces:

Total number of pieces - Number of black pieces = Number of white pieces

14 - 5 = 9

Therefore, there are 9 white pieces on the chessboard.

Proportion of White and Black Pieces

To calculate the proportion of white and black pieces, we divide the number of white pieces by the total number of pieces:

Proportion of white pieces = Number of white pieces / Total number of pieces

9 / 14 ≈ 0.64

Therefore, the white pieces make up approximately 64% of all the pieces on the chessboard.

To calculate the proportion of black pieces, we divide the number of black pieces by the total number of pieces:

Proportion of black pieces = Number of black pieces / Total number of pieces

5 / 14 ≈ 0.36

Therefore, the black pieces make up approximately 36% of all the pieces on the chessboard.

Summary:

- The white pieces make up approximately 64% of all the pieces on the chessboard. - The black pieces make up approximately 36% of all the pieces on the chessboard.
