1. ⅔ and ⅘ $\frac{2}{3} \: and \: \frac{4}{5} \\ lcm \: of \: \: 3 \: and \: \: 5 \: \: is \: 15 \\ \frac{2 \times 5 = 10}{3 \times 5 = 15} \\ \frac{4 \times 3 = 12}{5 \times 3 = 15} \\ we \: may \: \: write \: as \frac{10}{15} \: \: as \: \: \frac{100}{150} \\ \frac{12}{15} \: as \: \: \frac{120}{150} \\ \\ 5 \: rational \: \: number \: \: are \\ \frac{101}{150} \: . \: \: \frac{102}{150} \: . \: \frac{103}{150} \: \: . \frac{104}{150} \: \: . \frac{105}{150}$
2. X-2=7 => X= 2+7 => X=9 (ii) 2x/3=18 => 2X=54 => X= 27
