I made these up, so I hope they make sense to you.
1. A leaf is 9 centimeters long.
2. The mass of my computer is 1.5 kilograms.
3. My sister is 4 feet tall.
4. My baby brother weighs only 5 pounds.
5. The length of that door is 2 feet.
Basically, "quantitative" means using numbers to describe something. If you need to know, qualitative means using words.
