Respuesta :
since they both have zeros. 5 times 4 is 20. then you just add the two zeros from 400 and the other two from 500. the answer is 200000.
200,000
Further explanation
Given:
50 x 4 = 200
Question:
Explain how knowing 50 x 4 = 200 helps you find 500 x 400.
The Process:
We know that, [tex]\boxed{ \ 500 = 5 \times 100 \ },[/tex] then [tex]\boxed{ \ 500 = 50 \times 10 \ }.[/tex]
And also, [tex]\boxed{ \ 400 = 4 \times 100 \ }[/tex]
Let us find out the value of 500 x 400 from 50 x 4 = 200.
[tex]\boxed{ \ 500 \times 400 = \ ? \ }[/tex]
[tex]\boxed{ \ 500 \times 400 = \ (5 \times 100) \times (4 \times 100) \ }[/tex]
[tex]\boxed{ \ 500 \times 400 = \ (50 \times 10) \times (4 \times 100) \ }[/tex]
[tex]\boxed{ \ 500 \times 400 = \ (50 \times 4) \times (10 \times 100) \ }[/tex]
[tex]\boxed{ \ 500 \times 400 = \ 200 \times (1,000) \ }[/tex]
[tex]\boxed{ \ 500 \times 400 = \ 200,000) \ }[/tex]
Thus, the product of 500 x 400 equal to 200,000.
