Use a number line to add 5/4+(−2/4).(1 point
To add 5/4 + (-2/4) using a number line, we start by marking 0 on the number line.
Then, we move 5/4 units to the right from 0, which brings us to the point 5/4.
Next, we need to add -2/4, which means we need to move 2/4 units to the left from 5/4.
Since 2/4 is equivalent to 1/2, we move 1/2 units to the left from 5/4, which brings us to the point 3/4.
So, 5/4 + (-2/4) is equal to 3/4.
To add 5/4 and -2/4 using a number line, you can follow these steps:
Step 1: Start at 0 on the number line.
Step 2: Move 5/4 units to the right from 0.
Step 3: Since 5/4 is a positive number, the movement goes to the right.
Step 4: Your new position on the number line is at 5/4.
Step 5: Now, starting from the position obtained in step 4, move -2/4 units to the left.
Step 6: Since -2/4 is a negative number, the movement goes to the left.
Step 7: Your final position on the number line is at 3/4.
Therefore, the sum of 5/4 + (-2/4) is 3/4.
