Inductive reasoning involves drawing up conclusions from our observations, e.g. Fishes live in water, and they have gills, so they can breathe in water. Simply put, it's just making sense of things that you know, kinda like the "put two and two together" statement.
Deductive reasoning involves making conclusions from two or more statements. Let's say X = Y, and Y = Z, which means X is also equal to Z. That's deductive reasoning.
Hope it's clear now?
