How long should the handle be?

Ben has a toy light saber, and he wants to construct one proportionally smaller than his. The light on his is 33 in, and the handle is 9 in. If the light on the smaller version is 11 in, how long should the handle be?

---

Set up and solve a proportion

x = handle length

9/33 = 11/x 
9x = 363  {cross-multiplied}
x = 40.3  {divided each side by 9}

The handle should be approximately 40.3 inches.
