Find 10% and 1% of numbers

Today we will learn how to find 10% and 1% of numbers. Math helps us solve problems and understand the world around us.

Rates compare two different quantities. A unit rate expresses the comparison per one unit: 60 miles per hour, $3.50 per pound. To find a unit rate, divide: 120 miles in 3 hours → 120 ÷ 3 = 40 miles per hour. Percentages are rates per 100: 10% = 10 per 100 = 0.10. Finding 10% is easy: move the decimal point one place left. Finding 1%: move it two places. Scale drawings use a ratio to represent real dimensions: a map at 1 inch = 50 miles means distances on the map are divided by the scale to find real distances. Rates and ratios appear in cooking, construction, science, and everyday comparisons.

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
