Question

Evren used 24 centimeters of tape to wrap 3 presents. How many presents would evren be able to wrap with 112 centimeters of tape ?

Answer 1

Hi, Daziraa! What you must do is create a proportion, an equation in which two ratios are set equal to each other, with each ratio denoted by the quantity of centimeters of tape to the quantity of presents, or vice versa.

24/3 = 112/x

(24)(x) = (3)(112)

24x = 336

x = 14

Evren would be able to create to wrap 14 presents with 112 centimeters of tape.
