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

Answer:
his mass before the race was 68.5kg
Step-by-step explanation:
let,his mass before the race was 'x'
By question,
x-2% of x =67.13
or,x- 2x/100=67.13
or, 98x/100=67.13
or,98x=67.13×100
or,98x=6713
or,x=6713÷98
or,x=68.5
thus,his mass before the race was 68.5 kg
Answer:
4 stacks of packages
4 * 4 = 16 pieces of pancake
Step-by-step explanation:
Maximum amount to spend ≤ $30
Milk chocolate = $3.25
Pancakes per stack = 5.50 (sold in stacks of 4)
Let number of stacks = s
In equality terms :
3.25 + 5.50s ≤ 30
5.50s ≤ 30 - 3.25
5.50s ≤ 26.75
s ≤ 26.75 / 5.50
s ≤ 4.86
Hence, 4 stacks of pancakes can be purchased
