2+ (12 5/8) + 7 ( 12 3/4) +5 (12 7/8) +5 (13) + 4 ( 13 1/8) S= ehh help meh

  285 3/4

Step-by-step explanation:

The distributive property applies to mixed numbers as well as to other kinds of expressions. It is convenient to treat the integer part of the problem separately from the fractional part, then add results.

  2+ (12 5/8) + 7 ( 12 3/4) +5 (12 7/8) +5 (13) + 4 ( 13 1/8)

  = 2 +12 + 7(12) +5(12) +5(13) +4(13) + (5/8 +7(3/4) +5(7/8) +4(1/8))

  = 2 +12(1 +7 +5) +13(5 +4) + (5/8 +21/4 +35/8 +4/8)

  = 2 +12(13) +13(9) + ((5 +35 +4)/8 +42/8)

  = 2 +(13)(12 +9) +86/8

  = 2 +(13)(21) +10 6/8

  = 12 3/4 + 273

  = 285 3/4
