group of children share 11 3/7 pizza each child receives 10/14 of a pizza. How many children are in the group​

There are 16 children.
Multiply 11 by 7 to get 77 and then add the 3. So that becomes 80. That was to find the improper fraction. Now that you have 80/7 you have to get the same denominator as 10/14. Luckily it’s easy to get to 14 from 7 you just multiply by 2, but whatever you do to the top you do to the bottom. So now you have 80x2 & 7x2 which is equal to 160 & 14. So your new improper fraction is 160/14 now you divide that number by how many each kid gets. 160/14 divided by 10/14 and your answer is 16.
