Question

What is greater, 7/9, or 7.81 times 10 to the 1 power?

Answer 1

7.81 times ten to the first power is greater because 7/9 is equal to .777777 repeating while 7.81 times ten to the first is equal to 78.1

Answer 2

Well:

`7.81*10^1=7.81*10=78.1`

Since
`(7)/(9)` is less than 1,
`7.81*10^(1)` is larger.
