Question

A gardener plans to plant 630 trees in 21 rows each containing the same number of trees, then how many trees will there be in each row?

Answer 1

Hint:
In this question, we have a total number of trees and total number of rows. To find the number of trees in each row such that each row has the same number of trees we will simply divide Total number of trees by Number of rows.

Complete step by step solution:
Number of trees = 630
Number of rows = 21
Number of trees in each row such that each row has same number of trees = $\dfrac{{Total\,number\,of\,trees}}{{Number\,of\,rows}}$
= $\dfrac{{630}}{{21}}$= 30 trees in each row

Thus, the number of trees in each row such that each row has the same number of trees is 30.

Note:
You have to be careful while dividing. You need to put the number of trees in the numerator and number of rows in the denominator. You have to put a number of trees in the numerator because you need to find the number of trees in each row.
