Jen pours out 6 ounces of water from a full bottle. She estimates that she poured out 20% of the water in the bottle. About how much water was in the full bottle? Explain or show your reasoning.
Well, first let's break down what we need to do. So the water has been poured out of the bottle and now there is 80% remaining, because 20% was poured out. And that 20% was 6 ounces worth of water, and we need to find how much water was in the full bottle before water had gotten poured out.
If 6 ounces of water was poured out, and that was 20%, then we would need to divide 100 by 20 to find how much we need to multiply 6 by. 100 divided by 20 is equal to 5, so then we would need to multiply 6 by 5
And 6 times 5 is equal to 30, so now we have our answer
The amount of water that was in the bottle before it got poured out was 30 ounces of water
