Use a number line to add 5/4+ parentheses -2/4
To add 5/4 + (-2/4), we can use a number line:
0 1 2 3 4
-4 |#!...............|...
-3 |.................|...
-2 |.................|...
-1 |.................|...
0 |.................|...
1 |............#!...|...
2 |.................|#!...
3 |.................|...
Starting at 0, we move to the right by 5/4. This brings us to the point 5/4.
Then, we move to the left by 2/4. This brings us to the point 3/4.
So, 5/4 + (-2/4) equals 3/4 on the number line.
To add 5/4 + (-2/4) using a number line, follow these steps:
Step 1: Draw a number line with zero in the middle.
Step 2: Mark a point at 5/4 to the right of zero.
Step 3: Since we need to add -2/4, mark a point two units to the left of the point you just marked.
Step 4: Draw an arrow from the point you just marked to the point representing 5/4.
Step 5: The sum of 5/4 + (-2/4) is the point that the arrow ends at on the number line.
Step 6: To find the sum, locate the point where the arrow ends and determine the value represented by that point on the number line.
In this case, the point where the arrow ends is 3/4.
Therefore, the sum of 5/4 + (-2/4) is 3/4.
