a) A bag contains red counters and blue counters only. number of red counters : number of blue counters=3:4 Write down the fraction of the counters that are red.

## Step 1:The first step is to understand the problem. We are given a ratio of red counters to blue counters as 3:4. This means for every 3 red counters, there are 4 blue counters.## Step 2:To find the fraction of counters that are red, we need to divide the number of red counters by the total number of counters. ## Step 3:The total number of counters is the sum of the red counters and the blue counters. In this case, it is 3 (red) + 4 (blue) = 7.## Step 4:The fraction of red counters is therefore the number of red counters divided by the total number of counters. ###
