A group consisting of 126 students and 7 chaperones is going on a field trip. Which of the following groups does not have the same ratio of students to chaperones?

c

Step-by-step explanation:

Here are the options

A 36 students and 2 chaperones B. 54 students and 3 chaperones O C 90 students and 4 chaperones D 108 students and 6 chaperones

We have to simply the ratio of students to chaperones to its lowest form .

126 : 7 = dividing number of students and chaperones by 7 gives :  18:1

36 : 2 = dividing number of students and chaperones by 2 gives : 18:1

54 : 3 = dividing number of students and chaperones by 3 gives : 18:1

90 : 4 = dividing number of students and chaperones by 4 gives : 22.5 : 1

108 : 6 = dividing number of students and chaperones by 6 gives : 18:1

It can be seen that it is only 90:4 that does not have the same ratio as that given in the question

in 4 days he will run   12/14
