Answer 2

`\boxed{ \bold{ \huge{ \boxed{ \sf{ - (10)/(27)}}}}}`

Explanation:

`\sf{ - 3 (1)/(3) / 9}`

Convert the mixed number into improper fraction

`\longrightarrow{ \sf{ - ( 3 * 3 + 1)/(3) / 9}}`

`\longrightarrow{ \sf{ - ( 9 + 1)/(3) / 9}}`

`\longrightarrow{ \sf{ - ( 10)/(3) / 9}}`

Multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

`\longrightarrow{ \sf{ - ( 10)/(3) * (1)/(9)}}`

To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator

`\longrightarrow{ \sf{ - (10 * 1)/(3 * 9)}}`

`\longrightarrow{ \sf{ - (10)/(27)}}`

Hope I helped!
