I have a simple math question that I'm trying to convert to a formula
OG11, problem 155 from DS:
Q:...if 3 liters of water are added to the bucket when it is half full of water, the amount of water in the bucket will increase by 1/3..
when they explain the answer they do so this way:
Q: "when 3 liters are added, the volume of water will increase by 1/3, which is equivalent to multiplying the present value by 4/3"
3 + 1/2c = 4/3(1/2c)
I understand the 3 + 1/2c.
My question to you is.. how is the 4/3 part equivalent to the "increasing by 1/3" part??
Can anyone give me a simple example demonstrating their reasoning? I'm a bit confused.. I tried to set up a sample problem using the above method but wasn't able to.
Thanks!!
