  1. No offense but I’m concerned for your level in maths, this looks like a math exercice for a student in elementary school :’)

    500÷10= 50 grams
    Each slice weighs 50 grams

    It is 170 calories per 100 grams.
    50 is half of 100. So each slice: 170÷2= 85 calories

    Each slice is 85 cals!
