Arrange the given ratios as indicated:
2:3, 3:5,4:9 in ascending order

Answer

To arrange the given ratios 2:3, 3:5, and 4:9 in ascending order, we will first convert each ratio into a decimal form by dividing the first number by the second number. Then, we will compare these decimal values to determine their order.

### Step-by-Step Solution:

1. **Convert the first ratio (2:3) to decimal:**
\[ \text{Value of } 2:3 = \frac{2}{3} \approx 0.6667 \]

2. **Convert the second ratio (3:5) to decimal:**
\[ \text{Value of } 3:5 = \frac{3}{5} = 0.6 \]

3. **Convert the third ratio (4:9) to decimal:**
\[ \text{Value of } 4:9 = \frac{4}{9} \approx 0.4444 \]

4. **Compare the decimal values:**
- \(0.4444\) (4:9) is the smallest.
- \(0.6\) (3:5) is the next.
- \(0.6667\) (2:3) is the largest.

5. **Arrange the ratios in ascending order:**
- The order from smallest to largest is:
\[ 4:9, 3:5, 2:3 \]

### Final Answer:
The ratios in ascending order are: **4:9, 3:5, 2:3**
