Answer 1

Answer:

120 students did Jada survey

Step-by-step explanation:

* Lets explain how to solve the problem

- The results of Jada survey are shown in this circle graph

# Communication tools Text messages 5/12

# Phone 1/5

# Emails 1/20

# Other messaging apps 1/3

- A total of 50 students said they favored text messages to

 communicate with friends

- We need to find the total number of the students in Jada survey

- Assume that the total number of the students in the survey is x

∵ The Communication tools Text messages expressed by a

  fraction 5/12 of the circle graph

∵ The total of 50 students said they favored text messages to

   communicate with friends

- That means The fraction $\frac{5}{12}$ of x equivalent to 50

∴ $\frac{5}{12}*x=50$

- Multiply both sides by 12

∴ 5x = 600

- Divide both sides by 5

∴ x = 120

∵ x represents the number of the students in Jada survey

∴ 120 students did Jada survey
