(4.5 * 10^5)/(0.09 * 10 ^ 3)

The above can be simplified to (45 * 10 ^ 4) / (9 * 10 ) => 5000

Therefore 10 times of 5000 will be 50000

Answer is B. 50,000

Which of the following is 10 times the fraction \(\frac{4.5*10^5}{0.09*10^3}\)?

A. 500,000
B. 50,000
C. 5,000
D. 500
E. 5



\(\frac{4.5*10^5}{0.09*10^3}\)

=\(\frac{4.5*(10^2)}{0.09}\)

=\(\frac{450}{0.09}\)

= 5000

10 times the fraction will be 50,000.

Answer is B.

B is my choice
Time taken: 1:02
Here you go
4.5*10^5/0.09*10^3
45*10^4/9*10
45*10^3/9
5*10^3
5000 (to make it 10 times multiply by 10)
50,000
