Question

. A science fair has 405 projects. The coordinator

displays the projects in rows of 42. How many
rows have exactly 42 projects?

Answer 1

To find the number of rows that have exactly 42 projects, we can divide the total number of projects by the number of projects in each row. 10 rows have exactly 42 projects.

Step-by-step explanation:

To find the number of rows that have exactly 42 projects, we can divide the total number of projects by the number of projects in each row.

Number of rows = Total projects / Projects per row

Number of rows = 405 / 42

Number of rows = 9.64 (rounded to the nearest whole number)

Therefore, 10 rows have exactly 42 projects.

Answer 2

To get the answer, just divide, but you must not count in the rows that have less or more than 42 projects. 405/42=x

There are 9 rows that have exactly 42 projects because 42 x 9 = 378, which is the closest we can get to 405.

x = 9
