if nine counters are three -quarters of a set, how many counters are in one set

3/4 x = 9

x = 9 * 4/3
...

To find out how many counters are in one set, you need to determine the total number of counters represented by nine counters, which is three-quarters of a set.

First, let's set up the equation:

9 counters = 3/4 set

To find the total number of counters in one set, we can use algebraic manipulation. We'll multiply both sides of the equation by 4/3 to isolate the set on one side. Like this:

(9 counters) * (4/3) = (3/4 set) * (4/3)

On the left side, the counters cancel out, leaving us with:

(9 counters) * (4/3) = 36/3 = 12

So, one set consists of 12 counters.
