The answer is six and three fifths or 6 and 3/5 :D
To calculate three fourths minus one tenth, first convert both fractions to a common denominator. The least common denominator of 4 and 10 is 20. Thus, three fourths becomes 15/20 and one tenth becomes 2/20. Subtracting these gives 15/20 - 2/20 = 13/20. Therefore, three fourths minus one tenth equals 13/20.
