The LCD of 24 and 23 is 552, so 276/552 - 240/552 = 36. After simplifying 36/552, you get 3/46 and that is your answer.
Check the picture below.
make sure your calculator is in Degree mode.
You need to divide the top number by the bottom number and you will get your answer
First you would need to dive what you have of each ingredient by how much you need for 6 people.
Flour: 450 ÷ 150 = 3
Sugar: 380 ÷150 = 2
Cocoa: 300 ÷ 120 = 2.5
Eggs: 8 ÷ 3 = 2.7
then you look at the total batches each could make and average it to 2 batches. then multiply 6 by 2.
6×2= 12
so all together, the maximum amount of people you can make for is 12.
