We may make use of only mathematical operations like + , -, ×, and /

## Answer: 8 possible ways are there to convert six 9's into 100.

There can be multiple approaches to solve this problem by making use of various mathematical operations.

**Explanation:**

Various possible alternatives to make this equation are given below.

- 9 × 9 + 9 + 9 + 9 / 9 = 100
- 99 + 99 / 99 = 100
- (99 + 9 / 9) × 9 / 9 = 100
- (99 + 9 / 9) + 9 - 9 = 100
- (9 + 9 / 9) × (9 + 9 / 9) = 100
- (999 - 99) / 9 = 100
- 99 / 9 × 9 + 9 / 9 = 100
- (99 + 9 / 9) / (9 / 9) = 100

8 possible ways are there to convert six 9's into 100.

### Hence, we can make six 9's equal to 100 in these 8 ways.
