A room is 9 feet wide and 15 feet long. What is the ratio of its:
length to its breadth ?

Answer

To find the ratio of the length to the breadth of the room, we can follow these steps:

### Step 1: Identify the dimensions of the room
- The length of the room is given as 15 feet.
- The breadth (or width) of the room is given as 9 feet.

### Step 2: Write the ratio of length to breadth
- The ratio of length to breadth can be expressed as:
\[ \text{Ratio} = \frac{\text{Length}}{\text{Breadth}} = \frac{15 \text{ feet}}{9 \text{ feet}} \]

### Step 3: Simplify the ratio
- Since both the numerator and the denominator are in feet, we can cancel the units:
\[ \frac{15}{9} \]
- Now, we simplify the fraction by finding the greatest common divisor (GCD) of 15 and 9, which is 3.
- Divide both the numerator and the denominator by 3:
\[ \frac{15 \div 3}{9 \div 3} = \frac{5}{3} \]

### Final Answer
- The ratio of the length to the breadth of the room is:
\[ \frac{5}{3} \]
