Lucas spends 72 minutes cleaning his room. This is 8 times as long as it takes him to wash the dishes. How long does it take Lucas to wash the dishes?

It takes Lucas 9 minutes to wash the dishes

Step-by-step explanation:

In this question, we are tasked with calculating the number of minutes it will take Lucas to wash the dishes given the amount of time he spends on cleaning his room.

since we do not know the amount of time it will take, we can represent this with t

Now what information do we have? we are told that this time t multiplied by 8 will be equal to the time in minutes he takes to clean his room.

Hence, mathematically, we have 8t = 72 minutes

t = 72/8

t = 9 minutes
