Practice 7-6

Answer 1

1. 6th Floor

2. 13 cm

3. 15 boxes

4. $76.88

5. 14

Explanation:

1. 14 + 4 = 18. 18 - 6 = 12. 12 + 9 = 21. 21 - 15 = 6

2. 208 ÷ 16 = 13

3. 21 - 15 = 6. 6 + 30 = 36. 36 - 27 = 9. 9 + 22 = 31. 31 - 16 = 15

4. 138.75 + 115.07 = 253.82. 253.82 - 176.94 = 76.88

5. ? + 7 + 4 - 5 + 21 - 2 + 4 = 43. First you need to combine all of it:

? + 29 = 43. 43 - 29 = ?

43 - 29 = 14

? = 14
