Answer:
30 students
100 ÷ 20 = 50
60 ÷ 2 = 30 students
30 of the 50 students are 12 years old.
Step-by-step explanation:
60% of 50
60 : 100
X : 50
60/100 × 50
3/5 × 50 = 30
Answer:
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.
