Answer 2

It looks like you've provided a list of mathematical expressions and asked for some clarification or explanation for each of them. It appears that these are division operations involving multiplication of numbers. Let's go through each expression:

1. (35・18) : 7: Result: (35 * 18) / 7 = 630 / 7 = 90

2. (48・13) : 12: Result: (48 * 13) / 12 = 624 / 12 = 52

3. (99・14) : 14: Result: (99 * 14) / 14 = 1386 / 14 = 99

4. (5・12・70) : 14: Result: (5 * 12 * 70) / 14 = 4200 / 14 = 300

5. (7・32・45) : 15: Result: (7 * 32 * 45) / 15 = 10080 / 15 = 672

6. (5・21・54) : 9: Result: (5 * 21 * 54) / 9 = 5670 / 9 = 630

These calculations involve multiplication of numbers followed by division by another number, giving you the final results provided above. If you have any specific questions about these calculations or if you need further explanations, feel free to ask!
