Question : The arrangement of the fractions $\frac{4}{3}, -\frac{2}{9}, -\frac{7}{8}, \frac{5}{12}$ in ascending order is _____.
Option 1: $–\frac{7}{8}, –\frac{2}{9}, \frac{5}{12}, \frac{4}{3}$
Option 2: $–\frac{7}{8}, –\frac{2}{9}, \frac{4}{3}, \frac{5}{12}$
Option 3: $–\frac{2}{9}, –\frac{7}{8}, \frac{5}{12}, \frac{4}{3}$
Option 4: $–\frac{2}{9}, –\frac{7}{8}, \frac{4}{3}, \frac{5}{12}$
Correct Answer: $–\frac{7}{8}, –\frac{2}{9}, \frac{5}{12}, \frac{4}{3}$
Solution : $\frac{4}{3}, -\frac{2}{9}, -\frac{7}{8}, \frac{5}{12}$ LCM of (3, 9, 8 and 12) = 72 Multiply 72 with each fraction, We get 96, –16, –63, 30 In ascending order (– 63 < – 16 < 30 < 96) ⇒ $-\frac{7}{8}, -\frac{2}{9}, \frac{5}{12}, \frac{4}{3}$ Hence,

Question : $\Delta ABC$ and $\Delta DEF$ are similar. Also $\angle A=\angle D$ and $\angle B=\angle E$. If $4AB=DE$ and $BC=\operatorname{12 cm}$, then $EF$ is equal to:
Option 1: $\operatorname{3 cm}$
Option 2: $\operatorname{24 cm}$
Option 3: $\operatorname{16 cm}$
Option 4: $\operatorname{48 cm}$
Correct Answer: $\operatorname{48 cm}$
Solution :
Given that $\Delta ABC\sim\Delta DEF$ and $4AB = DE$ Since the triangles are similar, the ratios of their corresponding sides are equal. $\frac{BC}{EF} = \frac{AB}{DE}$ $⇒\frac{12}{EF} = \frac{AB}{4AB}=\frac{1}{4}$ $\therefore EF = 12×4 = \operatorname{48 cm}$ Hence, the correct answer is $\operatorname{48 cm}$.
