Answer 1

Step-by-step explanation:

$(ii)( - 5 \times \frac{2}{15} ) - ( - 6 \div \frac{2}{9} ) \\ = ( - 5 \times \frac{2}{15} ) - ( - 6 \times \frac{9}{2} ) \\ = ( \frac{ - 2}{3} ) - ( - 27) \\ = \frac{ - 2}{3} + 27 \\ = \frac{ - 2 + 81}{3} \\ = \frac{79}{3} \\ \\ (iii)( \frac{ - 7}{8} + \frac{3}{4} ) \div ( - 2 \times \frac{3}{4} ) \\ = ( \frac{ - 7 + 6}{8} ) \div ( \frac{ - 3}{2} ) \\ = ( \frac{ - 1}{8} ) \div ( \frac{ - 3}{2} ) \\ = \frac{ - 1}{8} \times \frac{2}{ - 3} \\ = \frac{1}{12} \\ \\ (iv) \frac{ - 7}{4} - \frac{2}{3} + \frac{ - 11}{4} + 0 - \frac{19}{4} \\ =\frac{ - 7}{4} - \frac{2}{3} - \frac{ 11}{4} - \frac{19}{4} \\ = \frac{ - 7 - 8 - 11 - 19}{12} \\ = \frac{ - 45}{12}$
