Question

You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.68 cm. If a toothpick is 6.3 cm tall, how many toothpicks tall will your model be?

Answer 1

set up a proportion where 1 over 1.68=30 over x. cross multiply so that you have x=50.4. then divide 50.4 by 6.3 to get 8 toothpicks tall.

Answer 2

5.1047....
so the answer is around 5 toothpicks altogether
