To solve this problem, you can make a proportion:
3/900 = x/2100
In this case, the x represents the pounds that will be needed to cover 2,100 feet.
The first step is to cross multiply like this:
3 * 2100 = 900 * x
Now you can simply the equation.
6300 = 900x
Now you divide both sides by 900 to cancel it out.
7 = x
So, your answer is 7 pounds.
400+30+7. +0+4
3,000,000+500+40+3,000+2+1
Your answer is
B) 1/2
because there are 5 odd and 5 even numbers from 5 through 10, so it would be 1/2.
Glad I could help, and good luck!
