Dave heads off with tutu and ruler in hand to see if he can help. Dave has made two pieces of cake for himself and Fran, but cannot work out why Fran says his is eight times larger when all the sides are only twice the length of hers. While he tries to figure that one out, he heads off to a dance school to help them enlarge a logo and paint it on some t-shirts. With Dave gone, Fran is able to explain how to use a scale factor to work out new dimensions and enlarge different shapes. At the dance school Dave successfully enlarges the logo using a scale factor of three, but can't work out why, when he comes to paint the design on the t-shirt, he quickly runs out of ink. Back in the studio Fran demonstrates the relationship between length and area scale factors and suggests that maybe that was why Dave ran out of ink.\n
