6 students can plant a garden in 5 hours. How many additional students should they get to help if they need to finish the job in 3 hours instead of 5 hours?

The correct answer is 4

Explanation:

One of the ways to solve this mathematical problem is by using the rule of three because there are three pieces of information and one missing information. Below, I show the process step by step:

1. Consider the information provided and the missing information

6 students =  5 hours

     x           =  3  hours

2. Cross multiply to create a simple equation

5x = 18

3. Solve

x = 18 ÷ 5

x = 3.6

This means 3.6 students are required to plant the garden in 3 hours, and this can be rounded as 4 considering people or students cannot be counted using decimal numbers.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

answer: x=3 and y=4
