Answers:

1. 1; ? = 2109.375

2. 5;
? = (1.8 * 3.6)/0.9 = 1.8 * 4 = 7.2

3. 3;
? = (7897 + 4596 + 3128) / 30 = 15621 / 30 = 520.7

4. 2;

√? = (104 * 104)/ 338 = 32
? = 1024

5. 1;
? = 9880 – 9625 = (? * 750)/100

? = (255 * 100)/ 750 = 34

6. 4;

? = 47

7. 4;

? = 0.125

8. 2;
? = 853 × 31 = 26443

9. 2; ? = 370/10 = 37

10. 1; ? = 10819.2
