hiii!!!

here's ur answer...

$2. \: (a) \: 4 \: and \: 4 \frac{2}{3} \\ \\ 4 \: and \: \frac{14}{3} \\ \\ = \frac{4 \times 3}{1 \times 3} = \frac{12}{3} \\ \\ = \frac{12 \times 2}{3 \times 2} = \frac{24}{6} \\ \\ = \frac{14 \times 2}{3 \times 2} = \frac{28}{6} \\ \\ three \: rational \: numbers \: between \: them \\ are \: \frac{25}{6} \: \: \frac{26}{6} \: and \: \frac{27}{6} . \\ \\ (b) \: \frac{ - 1}{2} \: and \: - \frac{ - 1}{4} \\ \\ = \frac{ - 1 \times 2}{2 \times 2} = \frac{ - 2}{4} \\ \\ = \frac{ - 2 \times 4}{4 \times 4} = \frac{ - 8}{16} \\ \\ = \frac{ - 1 \times 4}{4 \times 4} = \frac{ - 4}{16} \\ \\ three \: rational \: numbers \: between \: them \\ are \: \frac{ - 5}{16} \: \: \frac{ - 6}{16} \: and \: \frac{ - 7}{16} . \\ \\ 2. \: (a) \: \frac{3}{5} \: and \: \frac{2}{3} \\ \\ = \frac{3 \times 3}{5 \times 3} = \frac{9}{15} \\ \\ = \frac{2 \times 5}{3 \times 5} = \frac{10}{15 } \\ \\ = \frac{9 \times 6}{15 \times 6} = \frac{54}{90} \\ \\ = \frac{10 \times 6}{15 \times 6} = \frac{60}{90} \\ \\ five \: rational \: numbers \: between \: them \\ are \: \frac{55}{90} \: \: \frac{56}{90} \: \: \frac{57}{90} \: \: \frac{58}{90} \: and \: \frac{59}{90} \\ \\ (b) \: - 2 \: and - 1 \frac{1}{2} \\ \\ - 1 \frac{1}{2} = \frac{ - 3}{2} \\ \\ = \frac{ - 2 \times 2}{1 \times 2} = \frac{ - 4}{2} \\ \\ = \frac{ - 4 \times 6}{2 \times 6} = \frac{ - 24}{12} \\ \\ = \frac{ - 3 \times 6}{2 \times 6} = \frac{ - 18}{12} \\ \\ five \: rational \: numbers \: between \: them \: \\ are \: \frac{ - 19}{12} \: \: \frac{ - 20}{12} \: \: \frac{ - 21}{12} \: \: \frac{ - 22}{12} \: and \: \frac{ - 23}{12} . \\ \\ 4. \: \frac{ - 3}{4} \: and \: \frac{5}{6} \\ \\ lcm \: of \: 4 \: and \: 6 = 12 \\ \\ \frac{ - 3 \times 3}{4 \times 3} = \frac{ - 9}{12} \\ \\ \frac{5 \times 2}{6 \times 2} = \frac{10}{12} \\ \\ ten \: rational \: numbers \: between \: them \: \\ are \: \frac{ - 8}{12} \: \: \frac{ - 7}{12} \: \: \frac{ - 6}{12} \: \: \frac{ - 5}{12} \: \: \frac{ - 4}{12} \: \: \frac{ - 3}{12} \: \: \frac{ - 2}{12} \: \: \frac{ - 1}{12} \\ \frac{1}{12} \: \: \frac{2}{12} \: etc. \\ \\ sorry \: i \: do \: not \: know \: to \: find \: rational \: \\ numbers \: between \: two \: numbers \: and \: \\ are \: not \: fractions. \: so \: i \: have \: not \: solved \\ three \: question \: one \: is \: last \: one \: and \: other \: \\ two \: are \: last \: part \: of \: 2nd \: and \: 3rd. \\ \\ sorry \: but \: it \: may \: help \: you...$
