Rebekah needed exactly 6 cups of water for a recipe , but she had only 2 cups that could measure 5 cups and 8 cups of liquid respectively. How could she use these two to get the exact amount she needs
let the contents of the cups be
8 0
3 5
3 0
0 3
8 3
6 5
I still do not understand where did you get those numbers from?
Uh, well, I started out with no contents, then filled the 8-cup container. Then from the 8-cuo, I filled the 5-cup, leaving 3 and 5 cups in the two.
Then empty the 5-cup
pour the 3 cups from the 8-cup into the 5-cup
Refill the 8-cup
pour from it till the 5-cup is full, leaving 6 cups in the big container.
I mean geez, what else is there to do, except fill the cups, and pour the contents back and forth?
To get exactly 6 cups of water using the measuring cups of 5 cups and 8 cups, Rebekah can follow these steps:
1. Start by filling the 8-cup measuring cup to its maximum capacity.
2. Pour the water from the 8-cup measuring cup into the 5-cup measuring cup until it is completely full. This will leave 3 cups of water in the 8-cup measuring cup.
3. Empty the 5-cup measuring cup back into a separate container, such as a bowl or jug.
4. Pour the remaining 3 cups of water from the 8-cup measuring cup into the 5-cup measuring cup. Now the 5-cup measuring cup will have exactly 3 cups of water.
5. Fill the 8-cup measuring cup to its maximum capacity again.
6. Pour the water from the 8-cup measuring cup into the 5-cup measuring cup until it is completely full. This will leave 1 cup of water in the 8-cup measuring cup.
7. Empty the 5-cup measuring cup back into the separate container.
8. Finally, pour the 1 cup of water from the 8-cup measuring cup into the 5-cup measuring cup. Now the 5-cup measuring cup will have exactly 6 cups of water, which is the required amount.
By following this method, Rebekah can measure exactly 6 cups of water using the 5-cup and 8-cup measuring cups.
