Emily, Antonia, and Pablo each have an 8-inch pie divided into a certain number of pieces. Emily's apple pie was cut into 4 pieces
and she ate one of them. Antonia's cherry pie was cut into 20
pieces and she ate 4 of them. Pablo's pumpkin was cut into 40
pieces and he ate 10 of them.
Which two people have eaten the same amount of pie?

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
