Question

A scientist does an experiment with 12 plants he gives each plant exactly the same amount of water 1/5 liter how much water does he give the plants in all

Answer 1

If a scientist does an experiment where he puts 1/5 liters of water in 12 plants, and you want to see how much water he has put in all the plants together.

You would take 1/5 times 12

1/5*12=12/5

12/5 reduced would be 2 and 2/5 liters

2 and 2/5 liters of water in all plants

Hope this helps ;)
