Question

Karen wants to buy 5 pounds of baby carrots. The packages of carrots each weigh

14 ounces. How many will she need to buy to reach 5 pounds?

Use the number line to show how many packages she will need to buy.



Show the calculations to figure out how many packages she will need to buy.

Answer 1

6 packages.

Put it on the number line by labeling the leftmost point "1," put each point after that going up one number and then plot the point at 6.

Explanation:

Hello!

First, let's list an important conversion. 1 pound = 16 ounces.

For the sake of this explanation, and because I think this is mathematically easier to deal with, we are going to be dealing in ounces.

So, step one, convert 5 pounds to ounces. For this, we just multiply 5 by 16 to get 80.

Now, we know each package of carrots weighs 14 ounces each. Since we need to see how many times 14 goes into 80 (remember, 80 is the same as 5 pounds), we use division.

80/14 = 5
`(5)/(7)`

But, hey! You can/t buy 5/7ths of a package. So we need to buy an ENTIRE EXTRA PACKAGE just to make up for it.

So we round our number up to 6.
