Answer:
<em>33.75 red counters</em>
Step-by-step explanation:
Given the ratio of the red counters to blue counters as 5:4. The total ratio will be 5 + 4 = 9
If there are 27 blue counters in the bag, the total amount of counters there will be gotten using the expression;
4/9 * x = 27
x is the total counter in the bag.
4x/9 = 27
4x = 9*27
x = (9*27)/4
x = 60.75
The amount of red counters there will be
red counters = Total - blue counter
red counter = 60.75 - 27
<em>red counter = 33.75 red counters</em>
