60 : 2 = the number of students who are 12 years old.

60 : 2 = 30 students

30 of the 50 students are 12 years old.

Step-by-step explanation:

Change the percent to a decimal

.60 * 50 = 30

We can rewrite the decimal as a fraction

60/100 * 50

We can change the order

60 * 50/100

60 * 1/2

Multiplying by 1/2 is the same as dividing by 2

60 : 2 = the number of students who are 12 years old.

60 : 2 = 30 students

30 of the 50 students are 12 years old.
