Find the ratio of the following:
30 minutes to 1.5 hours

Answer

To find the ratio of 30 minutes to 1.5 hours, we will follow these steps:

### Step 1: Convert 1.5 hours into minutes
1. We know that 1 hour is equal to 60 minutes.
2. Therefore, to convert 1.5 hours into minutes, we multiply 1.5 by 60.
\[ 1.5 \text{ hours} = 1.5 \times 60 = 90 \text{ minutes} \]

### Step 2: Write the ratio
3. Now we can express the ratio of 30 minutes to 90 minutes.
\[ \text{Ratio} = 30 \text{ minutes} : 90 \text{ minutes} \]

### Step 3: Simplify the ratio
4. Since both quantities are in the same unit (minutes), we can simplify the ratio by dividing both sides by 30.
\[ \frac{30}{30} : \frac{90}{30} = 1 : 3 \]

### Final Answer
5. Therefore, the ratio of 30 minutes to 1.5 hours is:
\[ \text{Ratio} = 1 : 3 \]
