John went to the store to buy trail mix for a hike. He could buy 3 pounds of packages for $2.49 or 8 pounds of packages for $6.4
Lelechka [254]

<u>First what I did was find how much each pound would cost per different package. </u>

<u>So starting off with the 3 pound package. I did 2.49 divided by 3 to find out how much each pound would weigh. </u>

2.49 / 3 = 0 . 83

<u>So each pound in the 3 pounded package would cost $0.83. </u>

<u>Now to see how much the 8 pound package would cost. Just like the 3 pound package I had to find how much each pound would weigh. So I divided 6.49 by 8. </u>

6.49 / 8 = 0.81125

<u>So looking at the results the 3 pound package would be the best option. You are getting more for less. </u>

Tim has 2/3 cup of chocolate syrup. If he uses 1/9 cup of chocolate syrup for each serving of chocolate milk, how many servings
zimovet [89]

Answer:

6 servings

Step-by-step explanation:

Each serving Tim uses 1/9 cup. So, after using the amount of syrup reduces and repeated subtraction is division.

\frac{2}{3} ÷ \frac{1}{9}

=\dfrac{2}{3}*\dfrac{9}{1}

= 2 *3

= 6
