Step-by-step explanation:
1) 1 dozen=12 eggs
52 dozen = 52×12
=624 eggs
2) 12 muffins = 1 dozen
1 muffin = 1/12 dozen
75 muffins = 75/12
6.2 box
but three would be left so not 6.3 but 7 boxes
3) 1 student = 65 pencil
22 students = 22×64
=1430 pencil
1 student = 27 eraser
22 students = 22×27
= 594 eraser
Total = 1430+594
= 2024 items
4) 25 packs = 665 crayons
1 pack = 665=÷25
=26.6 packs
which means he bought 27packs
