Step-by-step explanation:

you would divide 300,000 to get 30,00. Then, you would multiply the 40,00 to get 400,00. So now your number is 430,000. After that, you would divide the 5,000 by 10 to get 500. Then you would take the 600 and multiply it by 10 to get 6,000. Then you would divide the 70 by 10 and get 7. your number is now 436,507. Lastly, you would multiply the 8 by 10 to get 80. So your final number is 436,587
