Human bones are 3/10 living tissues, 9/20 minerals,and the rest is water.What fraction of the human bone is water?

Sagot :

If 3/10 are living tissues and the minerals are 9/20 then:
3/10 = 6/20
9/20= 9/20
6/20 +  9/20= 15/20
20-15= 5
therefore 5/20 is the fraction of the human bone is water

[3/10+9/20]20
6/20+9/20=15/20
