Definition of Proportional
Two quantities are proportional if the ratio of their sizes is always the same.
For example, if the weight of a sausage is proportional to its length, doubling the weight of the sausage should also double its length, and vice versa.
As another example, the side lengths of the triangles in the picture are proportional to each other. Each side of the bigger triangle has twice the length of the corresponding side of the smaller triangle.
If you want to keep the two triangles proportional to each other and you triple the lengths of the sides of the smaller triangle, you will also have to triple the lengths of the sides of the larger triangle.
