Jessi consumes a diet of 1920 total kcalories that has 80 g of fat. what percent of jessi's diet comes from fat? (give answer to the appropriate reporting digit. only give the value. do not include the term percent or its abbreviation.)

37.5 % of diet

Fat provides 9 calories per gram.

so,

1 g = 9 calories and 80 g of fat = 720 calories.

Jessi consumes a diet consisting of total 1920 calories.

Percent of jessi's diet which comes from fat is,

( 720 / 1920 ) * 100 %

= ( 3 / 8 ) * 100 %

= 37.5 %

(Assuming diet is total of 1920 cal but if its 1920 Kcal then multiply 1920 * 1000 and then divide it by 720)
