Hello!
ANSWER:
36 students have a dog as a pet, and 30 students have a cat as a pet.
EXPLANATION:
Let's quickly convert these fractions to decimals by dividing their numerators by their denominators.
4 ÷ 5 = 0.8
2 ÷ 3 = 0.6666666667
Now, multiply the decimal forms by the number of students in Mrs. Hu's class.
0.8 × 45 = 36
0.(6)7 × 45 = 30

Answer:
n = 9
Step-by-step explanation:
3(n+7)=48
distribute
3n +21 = 48
subtract 21 from each side
3n = 48-21
3n = 27
divide by 3
3n/3 = 27/3
n = 9
It would be 15 because the 35 people at most minus the 20 students equals 15 so that would be the greatest number of adults allowed to be there.
