z góry dzienkuję

Answer 1

2 * 0.5 * 10 = 1 * 10 = 10

2 * 45.009 * 10 = 2 * 450.09 = 900.18

5 * 7.22 * 2 = 10 * 7.22 = 72.2

0.34 * 2 * 5 = 0.34 * 10 = 3.4

6.89 * 5 * 2 = 6.89 * 10 = 68.9

20 * 31.089 * 5 = 31.089 * 100 = 3108.9

50 * 0.00045 * 2 = 0.00045 * 100 = 0.045

200 * 1.99999 * 5 = 1.99999 * 1000 = 1999.99

50 * 0.12345 * 2 = 0.12345 * 100 = 12.345

200 * 0.0000078 * 500 = 0.0000078 * 100000 = 0.78
