Verified answer
Jawaban:
**1. 23+5x4:9-7**
```
= 23 + 5 * 4 / 9 - 7
= 23 + 20 / 9 - 7
= 23 + 2 (2/9) - 7
= 23 + 4/9 - 7
= 18 + 4/9
= 18 4/9
```
**2. 45x6+2-3:1**
```
= 45 * 6 + 2 - 3 / 1
= 270 + 2 - 3
= 271
```
**3. 98:2+6x4-6**
```
= 98 / 2 + 6 * 4 - 6
= 49 + 24 - 6
= 67
```
**4. (-122) + 14 - 9 x 7**
```
= -122 + 14 - 63
= -130
```
**5. (-15) : 5**
```
= -15 / 5 = -3
```
**6. 24 : 6 x 7**
```
= 24 / 6 * 7
= 4 * 7
= 28
```
**7. 69x6-24:4+6**
```
= 69 * 6 - 24 / 4 + 6
= 414 - 6 + 6
= 414
```
**8. 152-30+(-41)**
```
= 152 - 30 - 41
= 81
```
**9. 222-19x4:12**
```
= 222 - 19 * 4 / 12
= 222 - 38 / 3
= 222 - 12 2/3
= 209 2/3
```
**10. 86x9:7-4+4**
```
= 86 * 9 / 7 - 4 + 4
= 1204 / 7 - 4 + 4
= 172 - 4 + 4
= 172
```
Therefore, the answers are:
1. 18 4/9
2. 271
3. 67
4. -130
5. -3
6. 28
7. 414
8. 81
