0.3 part of the surface of a board is to be painted blue, 0.45 of its surface black and the remaining area, red. What portion of the board is to be painted red?

Answer:

To find the portion of the board to be painted red, we first add the portions to be painted blue and black to find the combined portion already accounted for:

Portion painted blue + Portion painted black = 0.3 + 0.45 = 0.75.

Since the sum of these portions is 0.75, the remaining portion to be painted red is:

Portion painted red = 1 - Portion painted blue - Portion painted black

Portion painted red = 1 - 0.75

Portion painted red = 0.25.

Thus, 0.25, or 25% of the board, is to be painted red.
