To solve each question, all you've got to do is add the two numbers together and then graph the result on the number line.
1.) -3 +(-1.5) Add 3 to -1.5. It would be the same as subtracting 1.5 from -3(-3 - 1.5) Final Answer: -4.5<span> Or, since you are using a number line, start on -3 and go left 1.5 units and you will land on the -4.5 point. You go to the left because you are adding a negative number.. </span> 2.) 1.5+3.5 Add<span> Final Answer: 5 </span>Or, since you are using a number line, start on 1.5 and go to the right 3.5 and you will land on 5. You go to the right because you are adding a positive number.<span>
</span>3.) 1/4 + 1/2 Multiply 1/2 by 2 to make both fractions have the same denominator 1/4 + 2/4 Add<span> Final Answer: 3/4 </span>Or, since you are using a number line, start on 1/4 and go up 2/4 and you will land on 3/4 as the result.<span>
</span>4.) -1 1/2 + (-1 1/2) Add -1 1/2 to -1 1/2. This would be the same as subtracting 1 1/2 from -1 1/2(-1 1/2 - 1 1/2)<span> Final Answer: -3 </span><span>Or, since you are using a number line, start on -1 1/2 and go to the left 1 1/2 and you will land on the -3 point.</span>
