Trenton Montgomery · Answer 1

90 kids are in mariahs school 50% is half so you multiply 45 by two

Pitts · Answer 2

Graders which have dogs = 50%

Number of graders having dogs = 45

Let the total number of students be 'x'

So, the equation would be

50% of x = 45

50/100 * x = 45

x = 45*100/50

x = 90 students
