4.08 x 10^2

0.97 x 10^2

Step-by-step explanation:

So 1st we'll want to divide 0.031 by 31 and do the rest the exact same

0.031 ÷ 31 = 0.001

0.501 ÷ 501 = 0.001

4.08 ÷ 408 = 0.01

0.97 ÷ 97 = 0.01

Now we'll want to multiply them to make sure we divided correctly

0.031 x 0.001 = 31

0.501 x 0.001 = 501

4.08 x 408 = 0.01

0.97 x 0.01 = 97

Now that we've confirmed we have divided correctly, we have to now continue multiplying / dividing.

0.031 x 10^2 = 3.1

0.501 x 10^2 = 50.1

4.08 x 10^2 = 408

0.97 x 10^2 = 97

Now we have to divide to make sure we are correct.

3.1 ÷ 10^2 = 0.031

50.1 ÷ 10^2 = 0.501

408 ÷ 10^2 = 4.08

96 ÷ 10^2 = 0.97

Our final step is figuring out which ones are true.

0.031 x 10^2 = 31 (FALSE)

0.501 x 10^2 = 501 (FALSE)

4.08 x 10^2 = 408 (TRUE)

0.97 x 10^2 = 97 (TRUE)
