The direction of mixing an insect spray to use 2 7/8 ounces of chemical in each gallon of water. how many ounces of chemical should be mixed with 6 1/3 gallons of water? first estimate the answer to the application problem. then find the exact answer.

Need approx 3 oz chemical to 1 gal water.
Conversion factor is then approx.      3 oz
                                                         
                                                           1 gal

Mult this result by 6 gal.  This gives you 18 oz, approx.

Now let's look for a more exact solution:

2.75 oz      19 gal
* = 17.4 oz.  The 18 oz estimate was close.
1 gal           3
