One serving of cottage cheese contains 14g of protein. This is 28% of the Recommended Daily Allowance of protein. How many grams of protein should one eat each day?

0.28x = 14
x = 14/0.28
x = 50g

You solve these and similar questions by restating the question: '14 is .28 (which is how you write 28 per cent) of what?' More mathematically, 14=.28x
to get x, divide both sides by .28.
14/.28 is 50
.28x/.28 is 1x
so 50 is 1x
x is your unknown (the 'what' in the question above)
So the answer is 50 grams.

14*100/28 = 50 g
preferably made up of items other than cottage cheese!

50 grams.
14g/.28 = x/1
14g = .28x
x = 14/.28
x = 50g.
