There is 278 calories for 100g of kiri cheese, each portion of kiri cheese has 46 calories. how many kiri portions do I need to equal 50g?

One needs 3.02 portions of kiri cheese to equal 50 g

Step-by-step explanation:

If there is 278 calories for every 100 g of the cheese, then 50 g of the cheese would contain half of that amount of calories, that is: in 50 g of kiri cheese, there is 278/2 = 139 calories.

since each portion has 46 calories, then  to reach to 139 calories (which is 50 g of the cheese) one needs 139/46 = 3.02 portions

ok
