Question

Amelia bought 144 centimeters of string to make beaded rings. If she needs 8 centimeters of string for each ring, how many rings can she make using the string she bought?

Answer 1

Amelia can make 18 rings out of the 144 centimeters of string.

Answer 2

She can make 18 rings using the string she bought.

We simply divide 144 centimeters by 8 centimeters to get the number of strings that can make the rings.

144 / 8 = 18 cm strings.

If you want to know the direct variation equation. then:

y = 8x where y is the total number centimeters to be bought; x is the number of rings to be made; while 8 is the constant of variation because 1 ring is made up of 8 cm of string.
