Hiya there!
If the recipe provided says that we need two cups for three gallons of punch, then you need 2/3 of a cup for one gallon.
I know this because if you add 2/3+2/3+2/3 (or multiply 2/3×3), you get the whole integer 3.
If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)
Answer:
18 inc wide is the qnswer
First of all, let's make the following observations:
15 is an integer, so in particular it is rational. The sum of two rational is rational. This means that is irrational if and only if is irrational.
Similarly, since 17 is rational and the multiplication of two rationals is rational, we have that is irrational if and only if is irrational.
The proof that is irrational is the following: suppose by contradiction that we could write
where a and b are two integers with no common factors.
Squaring both sides, we have
So, is a multiple of 3. This happens if and only if a itself is a multiple of 3. So, we can write and the expression becomes
So, is a multiple of 3 as well, and this happens if and only if b is itself a multiple of 3.
So, we started with the assumption that we could write as a reduced fraction, but this assumption led to a contradiction.
We deduce that is irrational, and so are and
