Respuesta :

The expression that is equal to 26.3 is 33 + 27.2 – (30.8) – 3.1

Let's find the expression that is equals to 26.3 .

33 + 27.2 – (6.8 + 24) – 3.1

using PEMDAS rule,

we have to resolve the part of the expression with parenthesis first.

Therefore,

(6.8 + 24) = 30.8

Then,

33 + 27.2 – (30.8) – 3.1

33 + 27.2 – 30.8 – 3.1

Then addition before subtraction according to the rule,

60.2 - 30.8 - 3.1

60.2 - 33.9 = 26.3

The answer should be 26.3 which is D
