D, it makes the most sense
well, 1/7th of the cupcakes is 3. so 2/7ths makes 6. and 21 minus 6 is 15. So, your answer is 15.
A boat with 13 gallons could travel 104 because 240 divided by 30 = 8 and then you do 8 x 13 = 104 miles. Hope this helps
•So here is our problem:
-15/3/5
So lets get started! :D
First you need to so 15/3=5
Now you have -5/5
-5/5= -1
So your answer to this problem is -1.
