Mixed Numbers

A mixed number is a combination of a whole number and a fraction. To represent a mixed number, you write the whole number part followed by the fraction part. For example, 5 2/7 means 5 whole units and 2 out of 7 parts of a unit.

Let's solve the given examples step by step:

1) 2 1/2 = 1 ?/2 To find the missing fraction, we need to subtract 1 from 2, which gives us 1. So the missing fraction is 1/2.

2) 14 5/12 = 13 ?/123 To find the missing fraction, we need to subtract 13 from 14, which gives us 1. So the missing fraction is 1/123.

3) 1 5/8 = ?/8 In this case, the missing whole number is 1. So the mixed number is 1 5/8.

4) 9 4/17 = 8 ?/? To find the missing fractions, we need to subtract 8 from 9, which gives us 1. So the missing fraction is 1/?.

5) 16 3/8 = ? ?/? In this case, we need to find both the missing whole number and the missing fraction. To do that, we subtract 8 from 16, which gives us 8. So the missing whole number is 8. The missing fraction is also 8/?.

6) 8 11/19 = ? ?/? Similar to the previous example, we need to find both the missing whole number and the missing fraction. To do that, we subtract 19 from 8, which is not possible. Therefore, there is no solution for this equation.

I hope this helps! Let me know if you have any further questions.
