Answer:

B.) 2 3/4 + (-4 1/4) = -1 2/4

Step-by-step explanation:

blue line: forward with positive +[tex]2\frac{3}{4}[/tex]

red line: backward with negative -[tex]4\frac{1}{4}[/tex]

so the number line follows: [tex]2\frac{3}{4}[/tex] + -[tex]4\frac{1}{4}[/tex] = -1 2/4

Step-by-step explanation:

Mark the end of arrows

  • 2-3/4
  • -4-1/4

So add them

[tex]\\ \tt\hookrightarrow 2\dfrac{3}{4}+(-4\dfrac{1}{4})=-1\dfrac{2}{4}[/tex]
