simplify

1 - \frac{1}{1 - \frac{1}{1 - \frac{2}{5}}}

\frac{5}{2}

Decimal Notation

2.5

Solution steps

1 - \frac{1}{1 - \frac{1}{1 - \frac{2}{5}}}

\frac{1}{1 - \frac{1}{1 - \frac{2}{5}}} = - \frac{3}{2}

= 1 - (- \frac{3}{2})

Apply rule

- (- a) = a

= 1 + \frac{3}{2}

Convert element to fraction:

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

= \frac{1 \cdot 2}{2} + \frac{3}{2}

Since the denominators are equal, combine the fractions:

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

= \frac{1 \cdot 2 + 3}{2}

1 \cdot 2 + 3 = 5

= \frac{5}{2}

y^{2} - 6 y + 34 = 0

(x + 3)^{2} < 2

[b + 6] + 6 = - 7

\frac{1}{3 + 2 i}

\frac{2 n - 8}{n ^{2} - 16}
