Solve: step by step explain!​

Answer 1

`(1)/(12)`

Explanation:

`\frac{ {c}^(2) }{3 \: . \: {b}^( - 2) } \\ \frac{ {1}^(2) }{3 \: . \: { ((1)/(2)) }^( - 2) } \\ \frac{1}{3 \: . \: \frac{1}{ {( (1)/(2)) }^(2) } } \\ (1)/(3 \: . \: (1)/( (1)/(4) ) ) \\ (1)/(3 \: . \: 1 \: . \: 4) \\ (1)/(12) \\`

`(1)/(3 \: . \: (1)/( (1)/(4) ) ) \\ (1)/(3 \: . \: 1 / (1)/(4) ) \\ (1)/(3 \: . \: 1 \: . \: 4) \\ (1)/(12)`
