convert.
9 meters = centimeters

Explanation:

Step1: Set up the proportion

We know that 1 meter is equal to 100 centimeters. To convert 9 meters to centimeters, we set up the proportion $\frac{100\text{ centimeters}}{1\text{ meter}}=\frac{9\text{ meters}}{x\text{ centimeters}}$. Cross - multiplying gives us $1\times x = 100\times9$.

Step2: Solve for x

$x=100\times9 = 900$.

900
