Answer:
find common denominator
1/5
2/3
common denominator is 15
convert 2/3 into a fraction with a denominator of 15
1/5 —> 3/15
2/3 —> multipky numerator and denominator by 5 —> 10/15 (toddlers)
infants = total - toddlers - preschoolers
infants = 15/15 - 10/15 - 3/15 = 2/15
multipky the fractions by 60 (the total number of students) to find for the number in each age group
(10/15)*60 = 40
(3/15)*60 = 12
(2/15)*60 = 8
