Question

What sum is represented by the following number line?

Answer 1

Step-by-step explanation:

Mark the end of arrows

• 2-3/4
• -4-1/4

So add them

$\\ \tt\hookrightarrow 2\dfrac{3}{4}+(-4\dfrac{1}{4})=-1\dfrac{2}{4}$

Answer 2

Answer:

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

Step-by-step explanation:

blue line: forward with positive +$2\frac{3}{4}$

red line: backward with negative -$4\frac{1}{4}$

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