Answer 1

7/16+1/4=11/16
25/36-2/9=17/36
5/7-11/21=4/21
1/6+5/18=8/18

Answer 2

Calculations with Fractions

Let's solve the given arithmetic problems involving fractions.

1. 7/16 + 1/4: To add these fractions, we need to find a common denominator, which is 16 in this case. Then we can add the numerators. The result is: ``` 7/16 + 1/4 = 14/16 + 4/16 = 18/16 = 9/8 ```

2. 25/36 - 2/9: To subtract these fractions, we also need a common denominator, which is 36 in this case. Then we can subtract the numerators. The result is: ``` 25/36 - 2/9 = 25/36 - 8/36 = 17/36 ```

3. 5/7 + 11/21: To add these fractions, we need a common denominator, which is 21 in this case. Then we can add the numerators. The result is: ``` 5/7 + 11/21 = 15/21 + 11/21 = 26/21 = 1 5/21 ```

4. 1/6 + 5/18: To add these fractions, we need a common denominator, which is 18 in this case. Then we can add the numerators. The result is: ``` 1/6 + 5/18 = 3/18 + 5/18 = 8/18 = 4/9 ```

I hope these examples help clarify how to perform arithmetic operations with fractions! If you have any more questions or need further assistance, feel free to ask!
