1 + 1 + \frac{1}{2.1}

2.47619 \dots

Solution steps

1 + 1 + \frac{1}{2.1}

Add the numbers:

1 + 1 = 2

= \frac{1}{2.1} + 2

Convert element to fraction:

2 = \frac{2 \cdot 2.1}{2.1}

= \frac{2 \cdot 2.1}{2.1} + \frac{1}{2.1}

Since the denominators are equal, combine the fractions:

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

= \frac{2 \cdot 2.1 + 1}{2.1}

2 \cdot 2.1 + 1 = 5.2

= \frac{5.2}{2.1}

Divide the numbers:

\frac{5.2}{2.1} = 2.47619 \dots

= 2.47619 \dots

(- 2) (- 5) (- 3)

(x^{2} + 1)^{- 1}
