Answer 1

To find the number of red marbles Henry has, divide the number of blue marbles by the denominator of the ratio and multiply by the numerator.

Step-by-step explanation:

To find the number of red marbles Henry has, we can use the given ratio and the number of blue marbles he has. The ratio of red marbles to blue marbles is 5:1. This means that for every 5 red marbles, there is 1 blue marble. Since Henry has 63 blue marbles, we divide this by the denominator of the ratio (1) and multiply by the numerator (5) to find the number of red marbles:

Red marbles = (63 blue marbles) x (5 red marbles / 1 blue marble) = 63 x 5 = 315.

Therefore, Henry has 315 red marbles. The correct answer is D) 25.
