Three out of every five students in a class 35 volunteer to help at the bake sale how many volunteered?

Three out of every five students in a class of 35 volunteer to help at the bake sale. To find the number of students who volunteered, we can calculate as follows:

Number of students who volunteered = (3 / 5) * 35

= (3 * 35) / 5

= 105 / 5

= 21

Therefore, 21 students volunteered to help at the bake sale.
