Understanding unit rates is an important skill for solving ratio problems, especially in Year 7 Math. So, what is a unit rate?

A unit rate is when you compare one quantity to one unit of another quantity. For example, if you buy 6 apples for $3, the unit rate is$0.50 per apple. Knowing this makes it easier to see which choices save you money.

Improving Your Skills with Ratios

1. Easier Comparisons: Unit rates help you compare different ratios more easily. For example, let’s say you have two kinds of juice. One costs $4 for 2 liters, and the other costs$6 for 3 liters.

   • For the first juice, the unit rate is $4 ÷ 2 =$2 per liter.
   • For the second juice, the unit rate is $6 ÷ 3 =$2 per liter. Both juices cost the same, so it makes your choice simpler!

2. Better Real-Life Decisions: Understanding unit rates can help you manage your money better in real life. If you see a bulk purchase deal, you can quickly calculate the unit rate to see if it’s cheaper than buying single items.

3. Building Blocks for Advanced Math: Knowing unit rates sets you up for more complicated math ideas like proportions and percentages.

By getting good at unit rates, you’ll be ready to tackle ratio problems confidently and face future math challenges!
