How can you use rates and ratios in real life situations? - Answers

For rate, an example would be a car moving at a rate of 3 mph or you would be making $6 per hour. That would be a really slow car, but that is just an example. For ratio, you would use it in baking. If you need 4 cups of flour and 3 cups of sugar, it would be 4:3, 4 to 3, or in fraction form 4 over 3. You can use this to double, triple, quadruple, or even quintuple a recipe if you have lots of people for supper. If you want to triple, 4x3 : 3x3 = 12:9, or 12 cups of flour, and 9 cups of sugar. You can also downsize a recipe. 4 devided by 2 : 3 devided by 2 = 2:1.5 or 2 cups of flour, and 1 and a half of sugar. Also aspect ratio for Computer Monitors can be important if you need to make the screen fit to your tv for example.
