APPLICATION Write a proportion for each problem, and solve for the unknown number.

a. Leaf-cutter ants that live in Central and South
America weigh about 1.5 grams (g). One ant can
carry a 4 g piece of leaf that is about the size of a dime.
If a person could carry proportionally as much as
the leaf-cutter ant, how much could a 55 kg algebra
student carry?

b. The leaf-cutter ant is about 1.27 cm long and takes
strides of length 0.84 cm. If a person could take
proportionally equivalent strides, what length strides
would a 1,65 m tall algebra student take?
