Liam has 5 kg of plant food. If he uses 25 g of food on each plant, how many plants can he feed?
1 answer:
Answer:
He can feed 200 plants
Step-by-step explanation:
First lets convert 25g to kg
25g = 0.025kg
Using proportion,
Let x be the number of plant he can feed
0.025kg = 1 plant
5kg = 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
At the left-hand side of the equation 0.025 will cancel-out 0.025 leaving us with just x while at the right-hand side of the equation 5 will be divioded by 0.025
x=200 plants
Therefore, he can feed 200 plants
