D) 0,000000007

E) 456.983

F) 0,000000673

Answer 1

To solve this problem, we need to write each number in two different ways, we could use percetanges or fractions.

(A) 40,000,000.00.

This number can be written in scientific notation like
`4 * 10^(7)`, where the exponent depends on the amount of zeros the quantity has.

A second way to write this number would be as a product
`2 * 20,000,000.00`.

(B) 0.02.

Similarly, this number can be written in scientific notation
`2 * 10^(-2)`, also, we can write it as a fraction
`(2)/(100)`.

(c) 105,000,000.

This number in scientific notation would be
`1.05 * 10^(8)`. As a product would be

`1050 * 100000`.

(d) 0.000000007.

In scientific notation would be
`7 * 10^(-9)`. As a fraction would be
`(7)/(1000000000)`.

(e) 456,983.

In scientific notation would be
`4.56983 * 10^(5)`. Also, we can write it as a sum

`450,000 + 6,983`

(f) 0.000000673.

In scientific notation would be
`6.73 * 10^(-7)`. As a fraction would be
`(673)/(1000000000)`
