To solve this expression, we need to follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) from left to right:

Start by simplifying the fractions:

29/35 + 32 = 29/35 + 32/1 = (291 + 3235)/(35*1) = (29 + 1120)/35 = 1149/357/20 - 12 = 7/20 - 12/1 = (71 - 1220)/(20*1) = (7 - 240)/20 = -233/205/28 - 73 = 5/28 - 73/1 = (51 - 7328)/(28*1) = (5-2044)/28 = -2039/2831/36 = 31/36

Recalculate the expression with the simplified fractions:

2:4/15*(55, 1149/35, -233/20, -2039/28, 31/36)

Perform the calculations:

Divide 2 by 4 to get 0.5: 0.5/15*(55, 1149/35, -233/20, -2039/28, 31/36)Multiply each term in the parentheses by 0.5:55 * 0.5 = 27.51149/35 0.5 = (1149 0.5)/35 = 574.5/35-233/20 0.5 = -233 0.5 / 20 = -116.5/20-2039/28 0.5 = -2039 0.5 / 28 = -1019.5/2831/36 0.5 = 31 0.5 / 36 = 15.5/36

Therefore, the final expression is:
27.5*(574.5/35,-116.5/20,-1019.5/28,15.5/36)
