Do the ratios `15 cm` to `2 m` and `10` sec to `3` minutes form a proportion?

Explanation

To determine if the ratios \(15 \, \text{cm}\) to \(2 \, \text{m}\) and \(10 \, \text{sec}\) to \(3 \, \text{minutes}\) form a proportion, we need to follow these steps:

### Step 1: Convert the units of the first ratio
We have the first ratio as \(15 \, \text{cm}\) to \(2 \, \text{m}\).
Since \(1 \, \text{m} = 100 \, \text{cm}\), we convert \(2 \, \text{m}\) to centimeters:
\[ 2 \, \text{m} = 2 \times 100 \, \text{cm} = 200 \, \text{cm} \]
