you use 4 gallons of water on 30 plants. At that rate how much water will you need for 45 plants?
you would use 6 gallons of water to water 45 plants
4=30
\(\frac{45}{30}\)=\(\frac{3}{2}\)
\(\frac{3}{2}\)of 4 gallons = 6 gallons
you will need 6 gallons for 45 plants. to find the answer you need to set up a proportion. 4/30=x/45. 45*4=180. 180/30=6
