Example 1.57 from Prealgebra, 1.5 Divide Whole Numbers

Divide Whole Numbers: example 1.57

Model the division: $24 \div 8 .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
To find the quotient $24 \div 8,$ we want to know how many groups of $8$ are in $24 .$

Model the dividend. Start with $24$ counters.

The divisor tell us the number of counters we want in each group. Form groups of $8$ counters.

Count the number of groups. There are $3$ groups.

$24 \div 8 = 3$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Model: $24 \div 6 .$
