Answer:
3.33333333 . . .
Step-by-step explanation:
Answer: 1 27
2. 54
9 243
10. 270
Step-by-step explanation: for one batch, the total minutes will be 15 + 12, so 27. Multiply 27 times b, the number of batches.
There may be another solution IF he is starting to prepare the next batch while the preceding is in the oven. Since this is not stated, I won't offer that solution here.
Any other irrational number. 0.4 is rational (ie., it can be written as a fraction), but rational+irrational is always irrational.
So examples would be π or √2. If you add those, the result is irrational.
Lets say... 7 divided by 21. ok? So... Just take 7, (usually the smaller number, but not in all cases.) and then multiply it by 1. 2. 3. So lets see. 7x1=7 so thats not it. 7x2 is 14 so thats not it. And you want to keep doing that until you get the other number. 7x3 is 21!!! That is the correct number so if you were doing long division like this
___3______ <--- the answer would be there.
7|21
