Boats

Three-quarters of boats are white, 1/7 are blue and 9 are red. How many boats do we have?

Result

n =  84

Solution:


3/4n + 1/7n + 9 = n

3n = 252

n = 84

An example in original writing: "three-quarters of boats are white, 4/7 are blue and 9 are red. How many boats do we have? " have no solution because of 3/4 + 4/7 = 37/28 > 1

And equation: 3/4n + 4/7n + 9 = n has negative solution n=-28
