First, perform the multiplication inside the parentheses204 • 405 = 82420
Now, add 137640 divided by 4137640 ÷ 4 = 344182420 + 34410 = 116830
Next, divide 454500 by 50454500 ÷ 50 = 9090
Finally, subtract the result of the division from the sum we calculated earlier116830 - 9090 = 107740
Therefore, (204•405+137640:4)-454500:50 = 107740.
