The colored parts in the picture below can all be represented by a quarter. Can you tell me why?

Answer: This is a topic in the understanding of grade three scores in primary schools. First of all, we must understand that 1/4 stands for a graph, which means dividing a graph into four parts on average and taking one of them. You can fold a piece of A4 paper in half and then fold it in half, so that each fold is a quarter of A4 paper. To guide children is to divide the whole 1( 1 piece of paper, an object, etc.). ) is divided into four parts on average (each part is equal in size), one part is 1/4, two parts are 1/2, three parts are 3/4, and four parts are the whole.
