Proportional reasoning relies on ratios. A key idea is that every ratio can be written as a fraction, and every fraction can be thought of as a ratio. Example: I make just 2/3 as much as my husband – this is thinking about it as a fraction.
To determine if two ratios are proportional, we cross multiply and check if the products are equal. In this case, 8 * 4 = 32 and 9 * 3 = 27. Since 32 is not equal to 27, the ratios 8 to 9 and 3 to 4 are not proportional.
Yes.

You multiply 4*16= 64. Then you take square root of 64. 8 is your answer.
it means to multiply 1/3 or what the problem is by the reciprocal so you flip it to multiply by 3/1

If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.

If he surveyed 45 students, it is not clear where the 15 came from, and conversely. 3/45 = 12/180 so the answer is 12.
In mathematics, deductive reasoning is used in proofs of geometric theorems. Inductive reasoning is used to simplify expressions and solve equations.
