hope it helps.....

Answer 2

Answer:

When 4.8 is divided by 100,we get 0.048 as solution and when 4.8 is divided by 1000,we get 0.0048 as solution.

Step-by-step explanation:

Given digit is 4.8.

Here we want do Division.

4.8 is a decimal number.

Now,

a)

$4.8 \div 100 \\ = \frac{4.8}{100} \\ = \frac{48}{100 \times 10} \\ = \frac{12}{25 \times 10} \\ = \frac{6}{25 \times 5} \\ = \frac{6}{125} \\ = 0.048$

b)

$4.8 \div 1000 \\ = \frac{4.8}{1000} \\ = \frac{48}{1000 \times 10} \\ = \frac{12}{250 \times 10} \\ = \frac{3}{125 \times 5} \\ = \frac{3}{625} \\ = 0.0048$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
