Question

1. There are 4 pounds of lawn seed to a bag. Three pounds of lawn seed covers 1800 square feet. How many bags are needed to cover 8400 square feet? Write and solve a proportion.
So the only part of the proportion I currently have written is: 1800/ = 8400/x
I'm not sure how to write 3 pounds out of 4 pounds to a bag. Which should be the denominator in 1800/.

2. Consider the proportions m/n = 1/2 and n/k = 2/5.
What is the ratio m/k?
4/1800 = x/8400

m/k = m/n * n/k = 1/5
