Arnie is 51/4 inches taller tha Ben, Ben is 37/8 inches shorter than Carlo, and Carlo is 21/4 inches shorter than Donell. Who is taller Arnie or Donell and by how much?l.

Answer 1

Step 1) Find the common denominator, which in this case is 8. This means:

Arnie is 201/8 taller than Ben

Ben is 37/8 shorter than Carlo

Carlo is 41/8 shorter than Darnell.

Step 2) Visualize. There are several ways to do this, I have jotted down one way below:

Arnie

+123

Darnell

+ 41

Carlos

+37

Ben

This is correct because 37+ 41+ 123 = 201 inches so Arnie is 201 inches taller than Ben.

So Arnie is the tallest, having 123/8 inches over Darnell. Simplified it is 15 and 3/8 inches.
