Question

Jon made an array that had 6 rows and 5 dots to solve a multiplication problem. He wants to make a bar diagram with equal parts that could solve the same problem. Which number should he put in each part of the bar model to represent the same problem array?

1) 5
2) 6
3) 30
4) 35

Answer 1

Jon's array represented 6 rows of 5 dots, which equals 30 dots in total. In a bar diagram with equal parts, each part should represent 5 dots to match the array's structure. Therefore, Jon should place the number 5 in each part of the bar model.

Step-by-step explanation:

Jon made an array with 6 rows and 5 dots to represent a multiplication problem. The array makes it easy to visualize the problem as 6 times 5, or 6 x 5. To solve the same problem using a bar diagram with equal parts, we need to create parts that represent the same total number of dots. Since there were 6 rows of 5, the product is 30, and this is the total number of dots in the array. Therefore, if we are to divide this total into equal parts in a bar diagram, each part on the bar diagram should represent the number of dots in a single row, which is 5. So, the number Jon should put in each part of the bar model to represent the same problem array is 5.
