Answer

To determine which number is smaller in each of the given pairs, we will analyze each pair step by step.

### Step-by-Step Solution:

**(i) 6, -7**
- Compare the two numbers: 6 is positive and -7 is negative.
- Since positive numbers are always greater than negative numbers, -7 is the smaller number.
**Answer:** -7

**(ii) 0, -1**
- Compare the two numbers: 0 is neither positive nor negative, while -1 is negative.
- Since negative numbers are smaller than zero, -1 is the smaller number.
**Answer:** -1

**(iii) -13, -27**
- Compare the two negative numbers: -13 and -27.
- The number further from zero in the negative direction is smaller. Here, -27 is further from zero than -13.
**Answer:** -27

**(iv) -26, 17**
- Compare the two numbers: -26 is negative and 17 is positive.
- Since negative numbers are always smaller than positive numbers, -26 is the smaller number.
**Answer:** -26

**(v) -317, -603**
- Compare the two negative numbers: -317 and -603.
- Again, the number further from zero in the negative direction is smaller. Here, -603 is further from zero than -317.
**Answer:** -603

**(vi) -777, 7**
- Compare the two numbers: -777 is negative and 7 is positive.
- Since negative numbers are always smaller than positive numbers, -777 is the smaller number.
**Answer:** -777
