PLEASE HELP Which shows the best use of the associative and commutative properties to make simplifying 34−5+9−24+2\frac{3}{4}-5+9-\frac{2} {4}+24
3−5+9−4
2+2 easier?
A.
[34+(−24)]+[9+2+(−5)][\frac{3}{4}+( -\frac{2}{4})]+[9+2+(-5)][4
3+(−4
2)]+[9+2+(−5)]
B.
[2+34+(−5)]+[(−24)+9][2+\frac{3}{4} +(-5)]+[(-\frac{2}{4})+9][2+4
3+(−5)]+[(−4
2)+9]
C.
[34+9+(−5)]+[2+(−24)][\frac{3}{4}+9 +(-5)]+[2+(-\frac{2}{4})][4
3+9+(−5)]+[2+(−4
2)]
D.
[34+(−5)]+[9+(−24)+2][\frac{3}{4}+( -5)]+[9+(-\frac{2}{4})+2][4
3+(−5)]+[9+(−4
2)+2]
