Cut the apple into pieces. You get 6/6, which is equal to 1 whole apple. Then after Nancy eats 2 of the slices, you subtract 2/6 from 6/6. After this you get 4/6.
4/6 is the fraction of the apple is left
Not sure if this is high school math though hahah

Answer:
sin(θ) = sin(θ + 2π) = -sin(-θ)
b and d
This can be shown by substituting a value for θ
sin(π ÷ 3) = 1/2
sin(π ÷ 3 + 2π) = 1/2
-sin(π ÷ 3) = -1/2
-sin(-π ÷ 3) = 1/2
sin(π ÷ 3 + π ÷ 2) = √3/2
21/25 can't be simplified because they do not have common number which they are divisible by.
