If a 10,000 gallon swimming pool requires 4 ounces of chemical, then how many ounces of chemical would be required for a 200 gallon swimming pool?

0.08 ounces of chemical for 200 gallons of water in the pool

Step-by-step explanation:

If for 10,000 gallons you need 4 ounces. You divide 4 ounces by 10,000 and get 0.0004. This means that for every gallon you need 0.0004 ounces.

So to know how much you'll need for 200 gallons all you have to do is multiply 200 by 0.0004 and you get 0.08 ounces for a 200 gallon pool

The easiest way to solve this problem is by writing it as a ratio.

So, if we write 10,000 and 4 as a ratio, we’ll get the ratio 10,000 to 4.

We can simplify this ratio by dividing both sides by 10,000 to get the ratio to its simplest form.

10,000 divided by 10,000 is 1

4 divided by 10,000 is .0004

Therefore, we know that for every gallon of pool, we will need .0004 ounces of chemical.

From there, we have to find how many ounces of chemical are needed in a 200-gallon pool, so we can again use our ratio by multiplying both sides by 200.

1 x 200 = 200

.0004 x 200 = .08

Therefore, for a 200-gallon pool, you would need .08 ounces of chemical.

Hope this helps! :)
