Explanation:
To make a 64-ounce batch of the cleaning solution, you can use the ratio provided in the instructions: 32 ounces of water to 4 ounces of concentrate.
The ratio of water to concentrate is 32 ounces : 4 ounces, which simplifies to 8 : 1 (if you divide both parts by 4).
To make a 64-ounce batch, you can simply multiply both parts of the ratio by 8:
8 (the ratio multiplier) x 32 ounces (water) = 256 ounces of water
8 (the ratio multiplier) x 4 ounces (concentrate) = 32 ounces of concentrate
So, to make a 64-ounce batch of the cleaning solution, you would need 32 ounces of concentrate.
