The fraction of number of bones in the body that are in your hands and skull is 0.35

Step-by-step explanation:

To solve the question firstly we list out the known variables as follows

Fraction of the number of bones in the skull to the total number of bones in the body = 0.1

Fraction of the number of bones in the hands to the total number of bones in the body = 0.25

Therefore, if the number of bones in the body = x, then number of bones in the skull = 0.1*x and number of bones in the hands is = 0.25 x

The sum of the total number of bones in the skull and hands is = 0.1x + 0.25x = 0.35x

The fraction of the total number of bones that is in the hands and skull = 0.35
