Answer 1

Answer: 78 ÷ 3 = 26

Explanation:

We are given that there are 3 groups shown. This means we will be dividing by 3.

We are given that each group has 2 ten rods (20) and 6 ones cubes (6). This means the answer is 26.

Lastly, 26 * 3 = 78, meaning we are dividing 78 by 3.

This gives us:

78 ÷ 3 = 26
