Answer:

4 1/4.

Step-by-step explanation:

First convert to improper fractions:

1 3/4 = (4*1 + 3)/4 = 7/4

2 1/2 = (2*2 + 1)/2 = 5/2

So it becomes:

7/4 + 5/2

The LCM of 2 and 4  is 4 so we write:

7/4 + 10/4

= 17/4

Now convert this to a mixed number:

17 / 4 = 4 remainder 1

So the answer is 4 1/4.

Answer:

4¼ is the answer

Step-by-step explanation:

[tex] \\ 1 \frac{3}{4} + 2\frac{1}{2} [/tex]

[tex] \\ \rightarrow \frac{7}{4} + \frac{5}{2} [/tex]

[tex] \\ \rightarrow\frac{7 + 10}{4} [/tex]

[tex] \\ \rightarrow \frac{17}{4} [/tex]

[tex] \\ \rightarrow 4\frac{1}{4} [/tex]

As we can see 17/4 is not divisible by 4 so if we divide it we will get decimal number or mixed number and we need the answer in mixed number so the number 4¼ is in the simplest form and is the answer.
