Dimas [21]

Using proportions, it is found that Felipe needs 23.625 meters of wood to make that many birdhouses.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

To make an amount, he needs 5 1/4 meters = 5.25 meters. How many meters he needs to make 4 1/2 = 4.5 times the amount?

5.25 x 4.5 = 23.625 meters.

Felipe needs 23.625 meters of wood to make that many birdhouses.
