To take 2/5 of 15, we have to multiply them.

`2/5 * 15`

To multiply, express 15 as a fraction.

`=2/5 * 15/1`

Then, cancel common factor between numerators and denominators.

`=2/1*3/1`

And, multiply straight across.

`=(2*3)/(1*1)`

`=6/1`

`=6`

Therefore, 6 is  ` 2/5`  of 15.

To find 2/5 of 15, you first turn 15 into a fraction: 

`2/5*15/1`

`=30/5`

You can simplify this down to 6/1which simplifies to 6.Therefore, the answer is 6.

In math, 'of' basically means multiplication. 

Therefore, this problem is trying to say that we have to multiple 2/5 by 15. 

`2/5 (15)`

Or.. 

`2/5(15/1)`

Multiply across.

`(2x15)/(5x1) = 30/5`

Simplify. 

`30/5 = 6`

Therefore, your answer is 6. I hope this helps!
