The adult need for dietary protein is 0.8 grams of protein per kilogram of body weight. yohan weighs 100 kilograms. how many grams of protein does he need to consume in order to meet his need?

80 grams

Explanation:

Given that 0.8 grams of dietary protein is needed per kilogram of the body weight of an adult, i.e. 0.8 g – 1 kg

We can let x represent the grams of protein needed by Yohan who weighs 100 kilograms, i.e. x – 100 kg

We have:  0.8 g – 1 kg

                  x – 100 kg

To find x, cross–multiply:

(100 × 0.8) / (1)x

x = (100 × 0.8)  

  = 80 g

Yohan needs to consume 80 grams of protein to meet his need.
