Question

Which number is greater than 555,621,000?A.5.0 x 10*6B.6.2 x 10*7C.5.55621 x 10*7D.9.99 x 10*6

Answer 1

Given:

`555,621,000`

Consider the individual options and compare them with the given number.

A.

`5.0*10^9`
`\text{Use }10^9=1,000,000,000.`

`5.0*10^9=5.0*1,000,000,000`

`5.0*10^9=5,000,000,000`

We know that

`5,000,000,000>555,621,000`

This option is correct.

B.

`6.2*10^7`

`\text{Use }10^7=10,000,000.`

`6.2*10^7=6.2*10,000,000`

`6.2*10^7=62,000,000`

We know that

`62,000,000<555,621,000`

This option is not correct.

C.

`5.55621*10^7`

`\text{Use }10^7=10,000,000.`

`5.55621*10^7=5.55621*10,000,000`

`5.55621*10^7=55,562,100`

`55,562,100<555,621,000`

This option is not correct.

D.

`9.99*10^6`

`\text{Use }10^6=1,000,000.`

`9.99*10^6=9.99*1,000,000`

`9.99*10^6=9,990,000`

`9,990,000<555,621,000`

This option is not correct.

Final answer:

`5.0*10^9\text{ is greater than 555,621,000.}`

Option A is correct.
