Question

Find the approximate result of the following expression (in whole numbers)

Answer 1

505.92 - 210.87 - 102.51

= 295.05 - 102.51

= 192.54

Answer 2

49.6 * 10.2  - 7.1 * 29.7 - 5.1 * 20.1 ≈ 190

Step-by-step explanation:

49.6 * 10.2  - 7.1 * 29.7 - 5.1 * 20.1

≈ 50 * 10  - 7 * 30  - 5 * 20

≈ 500 - 210 - 100

≈ 500 - 310

≈ 190

49.6 * 10.2  - 7.1 * 29.7 - 5.1 * 20.1 ≈ 190
