The answer to your question is 1.17 kg

Explanation:

Data

Percent of Calcium in human body = 1.4%

mass in kilograms = ?

weight of man = 185 pounds

Process

1.- Calculate the percent of Calcium in the man

                        185- pounds ------------------- 100 %

                           x                 -------------------  1.4%

                          x = (1.4 x 185) / 100

                          x = 259/100

                          x = 2.59 pounds

2.- Convert pounds to kilograms

                    1 kg -------------------- 2.2 pounds

                    x     --------------------- 2.59 pounds

                    x = (2.59 x 1) / 2.2

                    x = 1.17 kg
