Question

While in Canada, Renita bought a

souvenir that is 15 centimeters
long. She knows that 1 inch equals
3 centimeters. What is the length
of the souvenir in inches?

Answer 1

The length of the souvenir in inches is 5 inch ⇒ C

Explanation:

Let us solve the question using the ratio method

∵ The length of the souvenir is 15 centimeters long

∵ 1 inch equals 3 centimeters

→ By using the ratio method

→ inch : cm

→ 1 : 3

→ x : 15

→ By using the cross multiplication

∵ x × 3 = 1 × 15

∴ 3x = 15

→ Divide both sides by 3

∵
`(3x)/(3)` =
`(15)/(3)`

∴ x = 5

∵ x represents the length of the souvenir in inches

∴ The length of the souvenir in inches is 5 inch
