What percent is :
27 cm of 1.80 m

Answer

To find out what percent 27 cm is of 1.80 m, we can follow these steps:

### Step 1: Convert meters to centimeters
We need to convert 1.80 meters into centimeters since the two measurements must be in the same unit. We know that:
1 meter = 100 centimeters

So, to convert 1.80 meters to centimeters:
\[ 1.80 \, \text{m} = 1.80 \times 100 \, \text{cm} = 180 \, \text{cm} \]

### Step 2: Set up the fraction
Next, we need to find out what part 27 cm is of 180 cm. We can express this as a fraction:
\[ \frac{27 \, \text{cm}}{180 \, \text{cm}} \]

### Step 3: Convert the fraction to a percentage
To convert the fraction to a percentage, we multiply by 100:
\[ \frac{27}{180} \times 100 \]

### Step 4: Simplify the fraction
Before multiplying, we can simplify the fraction:
- Both 27 and 180 can be divided by 9:
\[ \frac{27 \div 9}{180 \div 9} = \frac{3}{20} \]

### Step 5: Multiply to find the percentage
Now we multiply by 100:
\[ \frac{3}{20} \times 100 = \frac{300}{20} = 15 \]

### Final Answer
Thus, 27 cm is 15% of 1.80 m.
