We need to add fractions 3/4 + 1 1/4 using number line.
First fraction is 3/4.
Please see, we have four small sections from 0 to 1.
3/4 represents three fourth. That is there part of four parts.
So, please plot a point at 3rd point from 0 between 0 and 1.
Then we need to add 1 1/4.
Let us see the fracion part 1/4.
1/4 represents one fourth part.
So, please move one more section from the point we plotted in above step.
We would be on exactly number 1 on the number line after this second step.
Now, we had 1 in front of the mixed fracion 1 1/4.
So, we need to move one number ( complete number) to the right of 1.
We will get on number 2 on number line.
So, the final answer for 3/4 + 1 1/4 is 2 using number line we drew.
