Multiple Choice

Ellie’s new kitten is $$4\frac{1}{2}$$   inches long. Her rabbit is $$3\frac{2}{5}$$   inches longer than her kitten. Which equation can be used to find the length of Ellie’s rabbit, r ?

•   $$4\frac{1}{2}-3\frac{2}{5}=r$$  

• $$r-3\frac{2}{5}=4\frac{1}{2}$$  

• $$4\frac{1}{2}-r=3\frac{2}{5}$$  

• $$3\frac{2}{5}+r=4\frac{1}{2}$$
