Question

Escreva de duas formas diferentes os números a seguir. Urgente

Answer 1

Answer:

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 $4 \times 10^{7}$, where the exponent depends on the amount of zeros the quantity has.

A second way to write this number would be as a product $2 \times 20,000,000.00$.

(B) 0.02.

Similarly, this number can be written in scientific notation $2 \times 10^{-2}$, also, we can write it as a fraction $\frac{2}{100}$.

(c) 105,000,000.

This number in scientific notation would be $1.05 \times 10^{8}$. As a product would be

$1050 \times 100000$.

(d) 0.000000007.

In scientific notation would be $7 \times 10^{-9}$. As a fraction would be $\frac{7}{1000000000}$.

(e) 456,983.

In scientific notation would be $4.56983 \times 10^{5}$. Also, we can write it as a sum

$450,000 + 6,983$

(f) 0.000000673.

In scientific notation would be $6.73 \times 10^{-7}$. As a fraction would be $\frac{673}{1000000000}$
