2)
1,700 gallons for 3 pumps
Divide 1,700 by 3 and we get what one pump does; 566 [tex]\frac{2}{3}[/tex]
We need 5,500 gallons, so we can divide by 566 [tex]\frac{2}{3}[/tex] for an answer of about 6.4782. You cannot have half of a pump, so our answer is 7 pumps.
3)
[tex]\frac{7fragments}{500tons} = \frac{100}{x}[/tex]
Cross multiply:
7 times x = 7x
500 times 100 = 50,000
50,000 = 7x
Divide both sides by 7:
7,142 tons of gravel = x
4)
Dozen = 12
12 divided by 3 (number of eggs) = 4
4 (batches you could make) times 4 (cookies made) = 16
So you could make 16 dozen cookies with a dozen eggs
I hope this helps, have a nice day :D
Hopefully you can read what the fractions say, they are formatted weird xD
