Respuesta :

no you can't multiplying by two I 's basically adding up two numbers till you get it

Yes, 7.5 can be multiplied by 2 to get 15.


Provided that number / 2 =/= imaginary number, then you can always multiply by two to reach said number.


Example 1)

8

8 / 2 = 4

4 * 2 = 8


Example 2)

4

4 / 2 = 2

2 * 2 = 4


Example 3)

15 / 2 = 7.5

7.5 * 2 = 15


Hopefully I haven't misinterpreted your question.
