Volume of dough = 2 and 3/4 cups = 2.75 cups Required for one dumpling = 3/16 cups = 0.1875 cups So, No. of dumplings = Total Volume of dough/Dough required for one dumpling = 2.75/0.1875 = 14.66666... He can make 14.7 dumplings.
So if John gives a pen and pencil to each and all of them are over we know that the no. of pencils and pens should be the same So we will find the LCM of 15 and 40 that is equal to 120 So John brought 120/15 that is 8 packets of pen and 120/40 that is three packets of pencils
