Well, that's vague. 2/15 is already in simplest form, so it can't be reduced further. In decimals, 2/15 is 0.13 (the 3 repeats). Multiplying both the numerator and denominator by the same number also gives us stuff like 4/30, 6/45, and 8/60.

Yes.
No.

2 over 5
10/15 = 2/3
It is: 10/15 = 2/3
6/15 which is the same as 2/5 is the equivalent to 0.4 as a decimal
