What is the length of the hypotenuse of the larger triangle?
I do not understand how to do this.

Ratio of 1:3 simply means that the corresponding sides of the larger triangle are 3 times as long as the smaller triangle.
If the hypotenust of the small triangle is 6 cm then the hypotenuse of the large triangle is 3*6 = 18 cm.

18 cm. Set up a proportion 1/3=6/L where L is the length of the larger hypotenuse. Invert your proportion to 3/1=L/6, and multiply by 6 to get 3/1*6=L=18 cm.

when the ratio of the lengths is 1:3, you know that no matter what the length of the ANY side of the smaller triangle, the larger traingle's corresponding side will be 3x as large as the smaller triangle's side. so, the length of the hypotenuse of the large triangle is 6*3=18cm
