Question

divide whole numbers, part 1 -- instruction -- level d
rowan collects 94 books to donate to his school. the books are divided equally among 4 classes. find how many books each class gets and how many books are left over.
$94\div4$
what is the greatest number of tens you can put in each group?
1 ten 2 tens 3 tens 4 tens

Explanation:

Step1: Calculate total tens in 94

94 has 9 tens (90 = 9×10)

Step2: Divide tens by 4 groups

$\frac{9}{4} = 2$ remainder $1$
This means we can put 2 tens in each group, since 2×4=8 tens (80) which is the largest multiple of 4 less than 9 tens.

Step3: Solve full division for context

$94 \div 4 = 23$ remainder $2$
Each class gets 23 books, 2 left over. But for the specific tens question, we focus on the tens division.

Answer:

2 tens
Additionally, for the full problem context: Each class gets 23 books, with 2 books left over.
