Answer:
15 students at school
Step-by-step explanation:
So there is 50 students in total
First subtract that much with how much students have the flu
1/10 = 5/50
So 5 students have the flu
That leaves 45 students
Then subtract that much with the amount of students that are remaining are on the field trip
45 divided by 3 = 15
so 2/3 = 30/45 (they can both be multiplied and divided by 15)
so 30 of the 45 students are on the field trip
45 - 30 = 15
That means there are 15 students left over at school
