Answer: 18080!
Step-by-step explanation:400 x 450
1. Multiplying from the oneths place ( turning 45.2 into 450)
2x0=0 2x0=0 2x4=8 = So the first answer is 800
2. Multiply from the tenths place
5 x 0 = 0 5 x 0 = 0 5 x 4 = 20 = the second answer is 2000
Multiplying the hundredths place
4 x 0 = 0 4 x 0 = 0 4 x 4 = 16 = The third answer is 1600
800 + 2000 + 1600 = 18080 Hope this helped! :)
