Answer 1

Step-by-step explanation:

given,

ratio of boys to girls= 3:7

what this means?

this basically means ( No. of boys)/( No. of girls)

so,

let number of boys be 3x and number of girls be 7x.

then

total number of students in Ms. Morales's class

= number of boys + number of girls

= 3x + 7x

= 10x

so, the answer should be a multiple of 10.

then, it is given that range is 22 to 34.

and within this range only 1 number is the multiple of 10 that is 30.

so,

Total number of students in ms. Morales's class is 30.
