Answer 2

`25.89`% is the percent of kilocalories in this meal that come from fat

Step-by-step explanation:

Amount of calories in one gram of carbohydrate
`= 4`

Amount of calories in one gram of protein
`= 4`

Amount of calories in one gram of fat

Now total calories in
`40` grams of protein

`= 40*4\\= 160`

Now total calories in
`25` grams of fat

`= 25*9\\= 225`

Total calories
`= 225 + 160+ 484\\= 869`

one kilocalories is equal to
`1000` gram calories

Total kilocalories is
`= 0.869`

Total kilocalories in fat
`= 0.0.225`

Thus, percent of kilocalories in this meal come from fat

`(0.225)/(0.869)* 100\\= 25.89`%
