Question

A school has 1605 students. If the students to teacher ratio is 15 to 1,how many teachers are there in the school?

Answer 1

Answer:

107

Step-by-step explanation:

let number of teachers=x

GIVEN students to teacher ratio is 15:1

so

15:1::1605:x

15*x=1605*1 ( product of means = product of extremes)

x = 1605/15

x = 107

therefore there are 107 teachers in the school.

Answer 2

Answer:

student= 1605

teacher=x

student to teacher rartio= 15 to 1

solution:

1605÷x=15÷1

15x=1605

x=1605÷15

so,teachers are 107
