Answer:
1:3
Explanation:
Total number of student's in Mr Johnson class = 24
If number of student that study Spanish = 18
Number of students that studied French = 24-18 = 6students
To get the ratio of students who study French to students who study Spanish, we will divide the total number of students who study French by that of students who study Spanish to have;
6/18
= 1/3 in its simplest form.
The ratio is therefore 1:3
Note that 'ratio' means division
