simplify (((30.03+0.21))/(30.42))-1

simplify

(\frac{( 30.03 + 0.21 )}{30.42}) - 1

- 0.00591 \dots

Solution steps

(\frac{30.03 + 0.21}{30.42}) - 1

Remove parentheses:

(a) = a

= \frac{30.03 + 0.21}{30.42} - 1

Add the numbers:

30.03 + 0.21 = 30.24

= \frac{30.24}{30.42} - 1

Convert element to fraction:

1 = \frac{1 \cdot 30.42}{30.42}

= - \frac{1 \cdot 30.42}{30.42} + \frac{30.24}{30.42}

Since the denominators are equal, combine the fractions:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{- 1 \cdot 30.42 + 30.24}{30.42}

- 1 \cdot 30.42 + 30.24 = - 0.18

= \frac{- 0.18}{30.42}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{0.18}{30.42}

Divide the numbers:

\frac{0.18}{30.42} = 0.00591 \dots

= - 0.00591 \dots

x^{2} + 2 x = - 4

\frac{3}{4} + \frac{6}{5}

\frac{2 x - 1}{x} > 0

9 x^{2} + 3 x - 4 = 0

4.6 + 1.2 x = 54.6 - 0.8 x
