Which example below uses deductive reasoning? . a.. using a pattern of dates to predict the next occurence of an event. b.. making a conjecture about triangles based on 3 examples. c.. creating the rule 3x+12 to describe a sequence of numbers. d.. declaring that squares have a certain property given that parallelograms have the same property

Deductive reasoning is a logical reasoning where a conclusion is based on the assurance of multiple parallels of that particular thing and are generally assumed to be true.

As per all the options given, here we can say that the correct answer is D. declaring that squares have a certain property given that parallelograms have the same property

60: 45 =12: 9 =4: 3 so the answer is 4: 3
