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.
