When should I use each of them? For example, in the following sentence, are they both okay? If neither is okay, what should we use?
Overall, people in all five nations allocate _____ of their income to food and drinks.
Note that here food and drinks constitute 35% of the total income, and it's the largest spending category given.
What if it were 51%? Would the answer change? Should we only use the major part and the majority when it accounts for more than 50% of the total? If that's the case, what should we use?
Thank you in advance!
