Correct question is "write the decimal form of the following rational number (- 1/4)"

Answer:

Decimal form of ( -  \frac{1}{4} ) is (-0.25)

Step-by-step explanation:

Here given rational number is ( -  \frac{1}{4} )

We want to convert this number into decimal number.

Given number is a proper fraction.

Now,

( -  \frac{1}{4} ) =  - (1 \div 4) \\  =  - 0.25

Therefore decimal form of ( -  \frac{1}{4} ) is (-0.25)

Similar problems:

We are taking a fraction  \frac{7}{8}

Now,

 \frac{7}{8}  \\  = 7 \div 8 \\  = 0.875

So, decimal form of  \frac{7}{8} is 0.875.

Again we are taking a fraction  \frac{9}{2}

Now,

 \frac{9}{2} \\    = 9 \div 2 \\  = 4.5

So, decimal form of  \frac{9}{2} is 4.5

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)
