No, 2/15 is in simplest form.
The way to check is to break each number apart into it's factors
2 = prime, so it's factors are 2 and 1
15 = 5 * 3
So, we have (2*1)/(5*3) Notice how no number on the top appears on the bottom, and vice-versa. This shows that the fraction cannot be reduced. If we had a similar number on top and bottom we could cancel those numbers and reduce the fraction. For instance:
12/30
12 = 6*2 = 3*3*2
30 = 10*3 = 5*3*2
So we have (3*3*2)/(5*3*2) We can cancel a 3 and a 2 since they appear both on the top and the bottom. Thus:
(3*3*2)/(5*3*2)
So, the left overs are:
3/5
nothing! it cant be reduced! nothing! it cant be reduced!
3/15 is equal to 1/5, therefore, 1/5 plus 1/5 would equal 2/5
one half or 1/2
reduced
Each number can be reduced by two, and no more. So 7:6.

Yes.
1/5 (one-fifth)
one and four fifthteenths
3/15 = three divided by 15 = 0.0667
nothing! it cant be reduced! nothing! it cant be reduced!
Yes because 7/15ths is less than a half of 15.
