The expression which is:
3.28 + 3.28 + 3.28 = 9.84
Is simply equivalent to the expression of thrice the value of 3.28 is equal to 9.84 or:
3 x 3.28 = 9.84
The two are simply equal since in the 1st expression there are three 3.28 and in the 2nd expression there are also three 3.28.
Answer with explanation:
→3.28+3.28+3.28
3.28 is added three times.

=9.84
You can solve the problem , without multiplying ,3.28 by 3 , that is add 3.28 three times.
3.28
3.28
3.28
+
------------
9.84
So, we have solved the problem by two ways,by Multiplication and Addition.
→If you solve it by multiplication , the missing factor will be =3 × 3.28
