Introduction
The length of a single room is obtained by dividing the entire length by total no of rooms. Here, we have a linear equation in one variable with unknown quantity on one side and the known quantity on the other.
Pre-Requisites:
Basic knowledge about arithmetic operations and linear equations
Activity:
The relation between unit conversions from kilometers to miles is a linear equation with the unknown miles on the linear expression side and the known kilometers in number side.
Real Life Question:
What is the length of single room if there are 30 rooms in a 150 meter long corridor?
