Order the following decimals from least to greatest: 1.23, 0.23, 0.2
Which is greater: 7/12 or 5/8? Explain by finding a common denominator or converting to decimals.
7/12 = 14/24 (multiply numerator and denominator by 2).
5/8 = 15/24 (multiply numerator and denominator by 3).
Since 14/24 < 15/24, 7/12 < 5/8.

A store sells packs of 9 pencils. If a teacher buys 7 packs, how many pencils does she have? If she shares them equally among 8 students, how many whole pencils does each student get?

Multi-step challenge: A school orders 720 crayons. They pack them into boxes of 10. Each classroom receives 3 boxes. How many classrooms get boxes, and how many crayons remain unpacked (if any)?
Boxes = 720 ÷ 10 = 72 boxes.
Each classroom receives 3 boxes → number of classrooms that can be given 3 boxes = 72 ÷ 3 = 24 classrooms.
Crayons remain = 0 (72 boxes used exactly).
