Question

there are 7 red marbles and 8 blue marbles in a bag.
(a) what is the ratio of all marbles in the bag to red marbles?

(b) what is the ratio of all marbles in the bag to blue marbles?

Explanation:

Step1: Find total marbles

Total marbles = Red + Blue = \(7 + 8 = 15\)

Step2: Solve part (a)

Ratio of all marbles to red marbles = \(15:7\) (or \(\frac{15}{7}\))

Step3: Solve part (b)

Ratio of all marbles to blue marbles = \(15:8\) (or \(\frac{15}{8}\))

Answer:

(a) \(15:7\)
(b) \(15:8\)
