Question

during a game of checkers, there is 16 pieces left. The ratio of black to red is 3:5 . How many black pieces are left on the board? Explain how you found the answer.

Answer 1

Since the ratio of the black to red is 3: 5

Then the total of the ratio is 3 + 5 = 8

Since there are 16 pieces left

By using the ratio method

black: red: total

3. : 5 : 8

x. : y : 16

By using cross multiplication

x x 8 = 3 x 16

8x = 48

Divide both sides by 8 to find x

x = 6

Since x represents the black left

The answer is 6 black left
