a) Proportional reasoning involves comparing quantities and their relationships.
b) Proportional reasoning relies on guesswork and estimation.
c) Proportional reasoning only applies to advanced mathematical problems.
d) Proportional reasoning is not a valid mathematical concept.

Answer 1

Proportional reasoning involves comparing quantities and their relationships. To solve a problem involving proportional reasoning, you need to identify the relationship between the quantities and set up a proportion equation.

Step-by-step explanation:

Proportional reasoning involves comparing quantities and their relationships. It is a mathematical concept that applies to a wide range of problems. Proportional relationships can be represented by ratios, rates, or proportions.

To solve a proportional reasoning problem, you need to identify the relationship between the quantities and set up a proportion equation. Then, you can solve the equation to find the unknown value. For example, if you know that 3 bananas cost $2, you can set up the proportion 3/2 = x/4 to find the cost of 4 bananas.
