Question

A group of students went on a field trip. There were 3 Boys for evrey 4 Girls in the group. if there were 20 girls, how many students in all went on the field trip?

Answer 1

35 students went on the field trip.

Step-by-step explanation

We are told that for this field trip,

3 boys = 4 girls

We are then told that there were 20 girls on the trip.

Let the number of boys on the trip be x

3 boys = 4 girls

x boys = 20 girls

We can form a mathematical relationship by cross multiplying

x × 4 = 3 × 20

4x = 60

Divide both sides by 4

(4x/4) = (60/4)

x = 15 boys

Total number of students that went on the trip = 15 boys + 20 girls = 35 students.

Hope this Helps!!!
