Question

If a 18 ft tall statue casts a 12 ft Long shadow, then how long is the shadow that a 3 ft tall baby elephant casts

Answer 1

2 ft

Explanation:

use cross multiplication

12 is to 18 as x is to 3

12 / 18 = x / 3

12 × 3 = 18x

now solve for x

36 = 18x

divide by 18

2 = x

So a 3 ft baby elephant casts a 2 ft shadow

Answer 2

2 feet

Explanation:

This is because you have to use ratios:

18:12 :: 3:x

you can then figure out 18/12=1.5, so you have to figure out what what 1/1.5 or 2/3 of what 3 is. you then multiply 3 by 2/3 and get 2 feet
