a protein bar has 15 grams of protein in a 40 gram bar. protein bar b has 20 grams of protein in a 60 gram bar. Which bar has more protein per gram.

15 g protein in 40 g bar has more protein/per g of bar

Step-by-step explanation:

15 g protein / 40 g = 3/8 protein/g

20 g protein / 60 g = 1/3 protein/g

We need to compare 3/8 and 1/3.

3/8 = 3*3/3*8 = 9/24

1/3 = 1*8/3*8 = 8/24

9/24 > 8/24, so 3/8 > 1/3
