As below.

Explanation:

37.8 + (-27.5) + (-26.8)

=> 37.8 - 27.5 - 26.8 Removing braces.

=> 37.8 - (27.5 + 26.8) Combining negative terms together.

color(white)(aaa aaa a) 27.5
color(white)(aaa aa) + 26.8
color(white)(aaa aaa a) --
color(white)(aaa aaa a) 54.3
color(white)(aaa aaa a) --

=> 37.8 - 54.3, From above, 27.5 + 26.8 = 54.3

color(white)(aaa aa) - 54.3
color(white)(aaa aaa aa) 37.8
color(white)(aaa aaa a)--
color(white)(aaa aa) - 16.5
color(white)(aaa aaa a)--
Hence the answer is 37.8 - 54.3 = color(blue)(- 16.5
