Question

Do this simplify step by step explanation. ​

Answer 1

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{1 - \frac{3}{ \frac{9}{1 - \frac{1}{2} } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{1 - \frac{3}{ \frac{9}{\frac{2 - 1}{2} } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{1 - \frac{3}{ \frac{9}{\frac{1}{2} } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{1 - \frac{3 \times 2}{{9 \times 1}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{1 - \frac{6}{{9}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{ \frac{9- 6}{{9}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{ \frac{3}{{9}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{2}{ \frac{5}{ \frac{1}{{3}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{2 \times 3}{ {5 \times 1}{{}{{}{}{ } } } } }$

$12 + \frac{1}{1 - \frac{6}{ {5 }{{}{{}{}{ } } } } }$

$12 + \frac{1}{ \frac{5- 6}{5} }$

$12 + \frac{1}{ \frac{ - 1}{5} }$

$12 + ( 1 \times - 5)$

$12 +( - 5)$

$12 - 5$

$7$
