To calculate this expression, we follow the order of operations (PEMDAS):
Start with the multiplication and division:7.6 0.25 = 1.925.8 0.5 = 12.9420 * 0.03 = 12.6
Now add and subtract the results from Step 1:1.9 + 290/1000 + 12.9 - 12.61.9 + 0.29 + 12.9 - 12.62.19 + 12.9 - 12.615.09 - 12.62.49
Therefore, the final result of the expression 7.6 x 0.25 + 290/1000 + 25.8 x 0.5 - 420 x 0.03 is 2.49.

25.8 0.5 = 12.9
420 * 0.03 = 12.6
Now add and subtract the results from Step 1:
1.9 + 290/1000 + 12.9 - 12.6
1.9 + 0.29 + 12.9 - 12.6
2.19 + 12.9 - 12.6
15.09 - 12.6
2.49
Therefore, the final result of the expression 7.6 x 0.25 + 290/1000 + 25.8 x 0.5 - 420 x 0.03 is 2.49.
