Question:

29 kilograms of fertilizer were bought for the garden. How many pounds of fertilizer were bought?

A 63.8 pounds
Explaination

Step 1:
Recall that 1kg = 2.2 pounds. We can use this information to set up the following proportionality equation:
(1kg) / (2.2 pounds)= (x pounds) / (29kg)
Step 2:
We can then use cross multiplication to solve for variable x:
(1 kg) × (x pounds ) = (29kg) × (2.2 pounds)
x = 63.8 pounds
63.8 pounds of fertilizer were bought for the garden.
