Answer:

Step-by-step explanation : human body contains 2/3 of water by mass

and asked us to find the percentage of water in person of mass 45kg

now first we should find the quantity of water i.e present in person of mass 45kg

= 2×45/3 = 30

to convert this value into % divide it by 100

= 30/100

= 0.3%

so % of water i.e present in a person of mass 45kg is 0.3%

I hope this is correct
