Sabrina gave 10 cookies to her brother. Her mother gave Sabrina half the number of cookies she gave her brother. Then Sabrina gave two-thirds of her cookies to her sister. If Sabrina had 20 cookies at the start, how many cookies are left with her?
Sabrina had 20 - 10 = <<20-10=10>>10 cookies left after giving 10 cookies to her brother.
Sabrina's mother gave her 10/2 = <<10/2=5>>5 cookies.
So, she had 10 + 5 = <<10+5=15>>15 cookies then.
She gave 15 x 2/3 = <<15*2/3=10>>10 cookies to her sister.
Therefore, she only has 15 - 10 = <<15-10=5>>5 cookies left.
