If twenty counters are a whole set, how many are in there in three-fifths of the set?
(3/5)*20 = 12 counters.
How many are in one set?
Divide 20 by 5.
How many are in three sets?
What will you do next?
To find out how many counters are in three-fifths of the set, we can set up a proportion.
Let x be the number of counters in three-fifths of the set.
We can set up the proportion as follows:
20 counters = 1 whole set
x counters = 3/5 of the set
We can cross-multiply to solve for x:
20 * (3/5) = x
20 * 3 = 5x
60 = 5x
x = 60 / 5
x = 12
Therefore, there are 12 counters in three-fifths of the set.
To find out how many counters are in three-fifths of a whole set, we first need to determine the total number of counters in one set. Since we know that twenty counters make a whole set, all we have to do is multiply twenty by the number of sets.
Let's assume there are 'x' sets in total. Therefore, the total number of counters is 20 * x.
Now, we want to find out how many counters are in three-fifths of the set. To do this, we take three-fifths of the total number of counters in one set. We can calculate this by multiplying the total number of counters (20 * x) by three-fifths (3/5).
The formula to calculate the number of counters in three-fifths of the set is:
Number of counters in three-fifths of the set = (20 * x) * (3/5)
By substituting 'x' with the actual number of sets, you can calculate the exact number of counters in three-fifths of the set.
