Question

There are 4 red counters and 3 blue counters in a bag. How many red counters do I need to add to the bag so that the ratio of red to blue counters is 3:1

Answer 1

Answer:

5

Step-by-step explanation:

Currently we have 4 red and 3 blue.

When we add red counters that implies that the blue ones don't change

Hence, finally we still have only 3 blue counters.

Therefore, to attain ratio of 3:1. We need 9 red counters.

Hence, we need to add 5 more red counters
