Answer 1

Answer:

${\tt{{\underline{\bold{\huge{Sᴏʟᴜᴛɪᴏɴ:}}}}}}$

$➪n \: + 3 \times \frac{1}{2} = 5 \times \frac{3}{4} \\ ➪ n + \frac{7}{2} = \frac{23}{4} \\ ➪n = \frac{23}{4} - \frac{7}{2} \\ ➪ n = \frac{23 \times 2}{4 \times 2} - \frac{7 \times 4}{2 \times 4} \\ ➪n = \frac{46}{8} - \frac{28}{8} \\ ➪n = \frac{46 - 28}{8} \\ ➪n = \frac{18}{8} \\ \\ ➪\frac{18}{8} \: in \: simplest \: form \\ ➪ \frac{18 \div 2}{8 \div 2} = \frac{9}{4}$
