Use a conversion factor. How many hours are there in one day?

9 days

Practice makes perfect

We know there are 24 hours (h) in 1 day. Therefore, we can create the following conversion factor. 1day/24h Multiplying 216 hours by this conversion factor will convert it to days.

216 h* 1day/24h

MoveLeftFacToNum

a*b/c= a* b/c

216 h * 1day/24h

Cross out common factors

216 h* 1 day/24 h

Simplify quotient

216 * 1day/24

Identity Property of Multiplication

216days/24

Calculate quotient
