How to do a math problem (similar triangles) in grade three, urgent ~
Because the triangle aef is similar to the triangle bce, AE: BC = AF: EB.

Because abcd is square, ad=bc=ab.

Because E is the midpoint of ab and AE: AB = 0.5, AE: BC = AF: EB = 0.5.

Because eb= 1/2ad af= 1/2eb, af= 1/4ad.

That is, AF/AD= 1/4.
