Question

(Adding and Subtracting Rational Numbers MC)

Solve 2.86 + (−14.6).

41.76
4.32
−17.46
−11.74

Answer 1

-11.74 is the correct answer. + (-) represents subtraction because plus times minus is minus. So right now, the expression would be 2.86 - 14.6. To solve, pretend that you are doing 14.6 - 2.86, which will give you 11.74. Plop the minus sign in front of it and there you go! You’d get - 11.74
