You buy 21 lbs of cucumbers which are 92% water. A few days later they’re 85% water. How much do they weigh then?
IrinaK [193]
To solve this, you must find the initial weight of the cucumber. To do this, you must divide the weight by the percentage of water and multiply it by 100.

(21/92)×100=22.83lbs.

Then, you multiply it by 85% and divide it by 100. Or simply multiply it by 0.85.

22.83×0.85=19.41lbs.
