Answer:
B
Step-by-step explanation:
This is just a matter of ratios.
Our first ratio is given. It is
3 carbs for every 4 fibers for every 7 protein.
Now, we just need to see what would happen if we replaced the fiber with 30!
Think about it this way. What do you need to do to get from 4 fibers(initial ratio) to 30 fibers? You multiply by 7.5
Now, since this is a ratio, everything must be proportional.
This given, we need to now multiply the carbs and the protein by 7.5, to make the ratio equal.
3*7.5=22.5
7*7.5=52.5
Final answer is now the new ratio:
22.5 carbs: 30 fibers: 52.5 protein.
If you simplify these, you will get right back to 3:4:7!
This is why the answer is B.
