Chocolate cake for 6 people needs 150g of flour, 150g of sugar, 120g of cocoa and 3 eggs. emma has 8 eggs, 450g flour, 380g sugar, 300g of cocoa. what’s the maximum number of people that she can make for a cake?

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.
