Ответ:
The least number of spoons = 11 spoons
The least number of forks = 6 forks
Step-by-step explanation:
We are told in the question:
Spoons only come in bags of 12
Forks only come in bags of 22.
This is an LCM question, hence, we find the Multiples of 12 and 22
The first common multiple is found and this is the lowest common multiple.
Multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156
Multiples of 22:
22, 44, 66, 88, 110, 132, 154, 176
Therefore,
LCM(12, 22) = 132
The least number of supplies she can have is 132.
So therefore,
The least number of spoons = 132 ÷ 12 bags of spoons = 11 spoons
The least number of forks = 132 ÷ 22 bags of forks = 6 spoons.

Answer with Step-by-step explanation:
28 said lunch was their favorite meal of the day.
18 women said their favorite meal of the day was lunch.
(28-18)=10 men will have lunch as their favorite meal.
33 said dinner was their favorite meal of the day.
19 men said their favorite meal of the day was dinner.
(33-19)=14 women will have favorite meal dinner.
There are total 36 women.
Total men=(76-36)=40
Women who like breakfast=(36-18-14)=4
Men who like breakfast=(40-10-19)=11
The table is shown below:
Men Women Total
Breakfast 11 4 15
Lunch 10 18 28
Dinner 19 14 33
Total 40 36 76
