Step-by-step explanation:

2a. 2/3^2 = 4/9 + 29/27. 9*3 = 27 so 4*3 = 12. 12+ 29 = 41. 41/27 = 1.58

2b. 2.5^3 = 15. 15-0.375 = 15.25 or 15 and 1/4

2c. -1.25^3 =1.56 and 1.56/.5^3 = 12.5 or 12 and 1/2

2d. 1.5^3 = 3/2^3 =27/8 + 6/8 = 33/8 or 4 and 1/8 divided by 593/50 or 11 and 23/25 = 0.35.

sorry I don't know how to do the rest.
