a total of 330 childern and adults attend a schoo, play.there were 21 times as many childern in the attends as there were adults

Question

i need to know how many children attended

Answer 1

330 = 21x + x

This equation can help you solve this problem, as x equals the number of adults and 21x represents the number of children. You can then solve by adding 21x + x and then dividing both sided of the equation by 22 to find x.

Then, you would multiply the number you found to be x by 21 to find the total number of children.
