Answer 2

★ Required Answer:-

Which of the following fractions are written in decreasing order?

• 3/4 , 1/2 , 2/5
• 1/2 , 2/5 , 3/4
• 3/4 , 2/5 , 1/2

★ Let's See:-

$\sf\dfrac{3}{4} + \dfrac{1}{2} + \dfrac{2}{5} \\ \\ \sf LCM = 20 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ = \sf\dfrac{3}{4} = \frac{3 \times 5}{4 \times 5} = \frac{15}{20 } \\ \\ = \sf\frac{1}{2} = \frac{1 \times 10}{2 \times 10} = \frac{10}{20} \\ \\ = \sf\frac{2}{5} = \frac{2 \times 4}{5 \times 4} = \frac{8}{20} \\ \\ = \sf\frac{3}{4} \: \: \boxed > \: \: \frac{1}{2} \: \: \boxed > \frac{2}{5} \: \: \: \:$

∴ Option [ 1 ] = 3/4, 1/2, 2/5 is correct. ✔
