Please help me!

What is four eights of six ninths and one half

7.47 / 3 = $_______ per pound

420 / 8 = $________ per hour

Sure, I can help you with that!

To write the cost of the grapes as a unit rate, we need to find the cost per pound.

We can do this by dividing the total cost of $7.47 by the number of pounds of grapes, which is 3 pounds.

So, the unit rate for the cost of the grapes is $2.49 per pound.

Now, let's move on to the next question.

To write Carla's family's average speed as a unit rate, we need to find the distance covered per hour.

We can do this by dividing the total distance of 420 miles by the total time of 8 hours.

So, the unit rate for Carla's family's average speed is 52.5 miles per hour.

I hope this helps! Let me know if you need any further assistance.
