Imagine a pizza. The pizza is 1. You cut the pizza into three slices: two slices are 1/4 (0.25) of the size of the pizza, the other slice is 2/4 (0.5) of the size of the pizza. We’ll ignore one of the 1/4 slices for this question, as we don’t need it.

Compare the 0.25 slice and the 0.5 slice, this problem is essentially asking “how many times can I fit the 0.5 slice into the 0.25 slice?”, the answer to this is obviously… 0, if you’re thinking in integers. Okay, but how much of the 0.5 slice could you fit in…? Half (0.5) of it. So 0.5 fits 0.5 times into 0.25.

Half of the slice that’s twice as big as the 0.25 slice fits into the 0.25 slice.

Edit: Gone back and read other comments and… Holy shit y’all, have some compassion for people who struggle with maths? Nobody is helped or motivated by snarky comments. A concept that is easy to grasp for you might be difficult to understand for someone else for a variety of reasons. Somewhat relevant xkcd.
