Answer:
1 1/2
Explanation:
We can illustrate the relationship between addition and subtraction using the following example:
If we have 5 - 3 = 2, then we can say that 2 + 3 = 5
So, in this case, the result of 3 1/4 - 1 3/4 is a number that added to 1 3/4 is equal to 3 1/4. Then, the answer will be 1 2/4 because:
[tex]1\frac{3}{4}+1\frac{2}{4}=\frac{7}{4}+\frac{6}{4}=\frac{13}{4}=3\frac{1}{4}[/tex]Because 1 3/4 is equivalent to 7/4 and 1 2/4 is equivalent to 6/4.
Finally, 2/4 is equivalent to 1/2, so we can rewrite the result 1 2/4 as follows:
1 2/4 = 1 1/2
Therefore, the answer is 1 1/2
