AVprozaik [17]

Answer: 11 batches of muffins

Step-by-step explanation:

From the question, we are given the information that Jim is baking chocolate chip muffins and that he has a total of 7 1/3 cups of chocolate chips, and each batch of muffins uses 2/3 of a cup of chocolate chips.

The most number of batches of muffins that Jim can make will be gotten by dividing 7 1/3 by 2/3. This will be:

= 7 1/3 ÷ 2/3

= 22/3 ÷ 2/3

= 22/3 × 3/2

= 11

Jim can make 11 batches of muffins.

If it takes 5 gallons of gas to drive 115 miles, how many miles can be driven using 7 gallons of gas?
elena-s [515]

Answer: The answer is 161

Step-by-step explanation: First you write 5 and 115 as a proportion, 5/115, (for every 5 gallons you can go 115 miles). Then you find out how much you can go with 1 gallon, divide by 5. Then multiply that by 7, since that is how many gallons you need to find out.

Hope this is helpful!
