Answer:
in my knowledge I think 13
we know the turtle is half as old as her parrot
so if we divide 10 by 3/4 we can get how old the turtle is
Basically we need to add and subtract 1/2 from 1/6:
(1) 1/6 - 1/2 = 1/6 - 3/6
= -2/6
= -1/3
(2) 1/6 + 1/2 = 1/6 + 3/6
= 4/6
= 2/3
Therefor the two numbers that are located 1/2 unit from 1/6 are -1/3 and 2/3
X to the 8/15 power. When you have a power raised to another power, you multiply the exponents.
