A cinama has 3 screens on last saturday the was 500 visitors 40% went to screen 1 25% went to screen 2 and the rest to screen 3
olga nikolaevna [1]

Answer:

The answer to your question is 200 visitors went to screen 1

                                                     125 visitors went to screen 2

                                                      175 visitors went to screen 3

Step-by-step explanation:

Data

3 screens

total number of visitors = 500

40% screen 1

25% screen 2

rest screen 3

Process

1.- Calculate the 40% of 500

                    500 visitors ------------------- 100%

                        x               -------------------    40%

                        x = (40 x 500) / 100

                        x = 20000/100

                        x = 200 visitors

2.- Calculate the 25% of 500

                     500 visitors ------------------- 100%

                        x                -------------------   25%

                        x = (25 x 500) / 100

                        x = 12500/100

                        x = 125

3.- Calculate the number of visitors to screen 3

                     500 - 200 - 125

                     175
