A bag contains blue and yellow counters.

ale4655 [162]

Answer:

5.25 : 1

Step-by-step explanation:

If 84% of the counters are blue, then 16% of the counters are yellow.

percentage of yellow counters = 100% - 84% = 16%

blue counters : yellow counters = 84 : 16 (we don't write %)

Now divide with 16, so the second number becomes 1.

$\frac{84}{16} : \frac{16}{16} = 5.25 : 1$
