Use and apply proportional relationships to solve problems. Determine and apply a constant of proportionality. Use proportions to solve scaling problems. Ratios and proportions are used in a wide variety of situations to make comparisons.
If one number in a proportion is unknown you can find that number by solving the proportion. Example. You know that to make 20 pancakes you have to use 2 eggs. How many eggs are needed to make 100 pancakes?
22 gru 2018 · esson: Solving Linear Equations. Take a look at this example to see how to solve a complicated proportions. Example: Solve this proportion. We know from our knowledge of proportions (see Proportions) that cross-products must be equal. So, cross-multiply. Cross-multiplying results with these two equal products.
Functions can be described by a rule in the form of y = mx + b, where m and b are constants. Constant rates and proportional relationships can be described by a function, specifically a linear function where the rule is a linear equation. Functions are described in terms of their inputs and outputs.
