Liam has 5 kg of plant food. If he uses 25 g of the food on each plant, how many plants can he feed?

He can feed 200 plants

Step-by-step explanation:

To solve this, we will follow the step below:

first, convert 25 g to kg

25 g = 25/1000 = 0.025 kg

Now using proportion to solve;

Let x be the number of food plant he can feed the plant

0.025 kg = 1

5 kg = x

cross-multiply

0.025*x = 5*1

0.025x = 5

Divide both-side of the equation by 0.025

0.025x/0.025 = 5/0.025

x=200 plants

Therefore, he can feed 200 plants
