Answer:
The answer to your question is 436.8 kcal of lipids
Explanation:
Data
Total number of calories = 1120 kcal
48 % carbohydrates
13 % proteins
? % lipids
Process
1.- Sum the percent of proteins and carbohydrates
             48% + 13% = 61 %
2.- Calculate the 61% of 1120
              1120 kcal -----------------  100%
                 x            -----------------   61%
                 x = (61 x 1120) / 100
                 x = 68320 / 100
                 x = 683.2 kcal
      683.2 kcal are proteins and carbohydrates
      kcal of lipids = 1120 - 683.2
                            = 436.8 kcal
