Answer 2

1) 7 + 3/10: To add 7 and 3/10, we need to find a common denominator for the two numbers. In this case, the common denominator is 10. We can rewrite 7 as 70/10, so the addition becomes:

70/10 + 3/10 = (70 + 3) / 10 = 73/10

So, 7 + 3/10 equals 73/10.

2) 8 + 13/100: Similarly, to add 8 and 13/100, we need to find a common denominator. In this case, the common denominator is 100. We can rewrite 8 as 800/100, so the addition becomes:

800/100 + 13/100 = (800 + 13) / 100 = 813/100

So, 8 + 13/100 equals 813/100.

3) 7/1000: There is no addition operation in this expression. 7/1000 is simply a fraction representing seven thousandths. It cannot be added to the previous expressions since they are in a different format.

4) 15 + 237/10,000: To add 15 and 237/10,000, we need to find a common denominator. In this case, the common denominator is 10,000. We can rewrite 15 as 15,000/10,000, so the addition becomes:

15,000/10,000 + 237/10,000 = (15,000 + 237) / 10,000 = 15,237/10,000

So, 15 + 237/10,000 equals 15,237/10,000.

In summary: 1) 7 + 3/10 = 73/10 2) 8 + 13/100 = 813/100 3) 7/1000 (fraction representing seven thousandths) 4) 15 + 237/10,000 = 15,237/10,000
