Formula used: An equation that equates two ratios or rates is called a proportion. Therefore, if b≠0 and d≠0, then: ab=cd is a proportion. Calculation: As it is provided that it is recommended that 7.8 mL of Grow-It-Right plant food be mixed with 2L of water for feeding house plants. Let x represent the amount of plant food that should be mixed with 1 gal or 3.8 L of water. Set up a proportion by writing two equivalent ratios: 7.8 mL2L=x mL3.8 L Multiply by LCD, that is 7.6. 7.6⋅7.8 mL2L=x mL3.8 L⋅7.6 7.8(3.8)=2x Solve the resulting linear equation as: 2x=29.64 x=14.82 Thus, there should be 14.82 mL of plant food mixed with 1 gal of water.
