<human>:  Neil baked 20 cookies. He gave 2/5 of the cookies to his friend. How many cookies are left for Neil?
<bot>: How many cookies did Neil give to his friend? ** Neil gave 20 x 2/5 = <<20*2/5=8>>8 cookies
How many cookies are left for Neil? ** So he is left with 20 - 8 = <<20-8=12>>12 cookies.
