Percent mass after dehydration?
99% of the mass of a watermelon is water. After the watermelon was lying in the sun it dried up some, and now contains only 98% water. By how many percent has the total mass of the watermelon decreased?
Thank you ☺

the "non-water" part which was previously 1% has now become 2%
which with a little thought will tell that total mass must have become 1/2 or 50%
ans: 50% decrease
