Question

To the nearest​ millimeter, a cell phone is 72 mm long and 46 mm wide. What is the ratio of the width to the​ length

Answer 1

Length = 72 mm

Width = 46 mm

Ratio = 72:46 = 36:23

Explanation:

72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.
