A unit rate helps us compare two different amounts by showing one amount as how much it costs for one unit.
For example, if you want to buy apples and they cost £4 for 2 kg, the unit rate is £2 for 1 kg. This makes it easier to understand prices and choose wisely.
Why Unit Rates Matter in Daily Life:
Shopping: When you're at the grocery store, checking unit prices (like £ per kg or £ per litre) can help you find the best deal. For instance, if Brand A is £5 for 1.5 kg and Brand B is £6 for 2 kg, you can find out the unit rates. Brand A costs about £3.33 for 1 kg while Brand B costs £3 for 1 kg.
Travel: Unit rates can also help us know how far we can go on a certain amount of fuel. If a car can travel 300 km using 10 litres of fuel, then the unit rate is 30 km for each litre.
Recipes: If a recipe needs 4 cups of flour to make 8 cookies, the unit rate shows that each cookie uses 0.5 cups of flour. This makes it easier if you want to change the recipe.
Knowing about unit rates helps us make smart choices in many parts of our everyday lives!
