    Answer:

    126 students

    Step-by-step explanation:

    Boys : Girls

    7 : 11

    How do you get from 7 to 49?

    49 ÷ 7 = 7

    Therefore, you should multiply the number of boys by 7.

    Multiply:

    7 : 11

    7 × 7 = 49

    49 : 11

    Remember that whatever we do to the left, do to the right.

    Multiply:

    49 : 11

    11 × 7 = 77

    49 : 77

    Now, let’s add the number of boys and girls in the class to find the total number of students.

    Add:

    49 + 77 = 126

    Therefore, there are 126 students in all.
