Answer 2

Answer:

$1. \: \: \frac{7}{4} > \frac{5}{6} > \frac{2}{3} > \frac{3}{5} > \frac{4}{7}$

$2. \: \: \frac{11}{14} > \frac{15}{28} > \frac{13}{35} > \frac{2}{7}$

Step-by-step explanation:

1. Find the LCM of the denominators

2 | 5, 6, 4, 3, 7

2 | 5, 3, 2, 3, 7

3 | 5, 3, 1, 3, 7

5 | 5, 1, 1, 1, 7

7 | 1, 1, 1, 1, 7

1, 1, 1, 1, 1

LCM of 5, 6, 4, 3 and 7 = 2×2×3×5×7 = 420

$\frac{3 \times 84}{5 \times 84} = \frac{252}{420}$

$\frac{5 \times 70}{6 \times 70} = \frac{350}{420}$

$\frac{7 \times 105}{4 \times 105} = \frac{735}{420}$

$\frac{2 \times 140}{3 \times 140} = \frac{280}{420}$

$\frac{4 \times 60}{7 \times 60} = \frac{240}{420}$

Now, arrange these in descending order

$\frac{735}{420} > \frac{350}{420} > \frac{280}{420} > \frac{252}{420} > \frac{240}{420}$

$\frac{7}{4} > \frac{5}{6} > \frac{2}{3} > \frac{3}{5} > \frac{4}{7}$

2. Find the LCM of the denominators

2 | 7, 14, 28, 35

2 | 7, 7, 14, 35

5 | 7, 7, 7, 35

7 | 7, 7, 7, 7

1, 1, 1, 1

LCM of 7, 14, 28, 35 = 2×2×5×7 = 140

$\frac{2 \times 20}{7 \times 20} = \frac{40}{140}$

$\frac{11 \times 10}{14 \times 10} = \frac{110}{140}$

$\frac{15 \times 5}{28 \times 5} = \frac{75}{140}$

$\frac{13 \times 4}{35 \times 4} = \frac{52}{140}$

Now, arrange these in descending order

$\frac{110}{140} > \frac{75}{140} > \frac{52}{140} > \frac{40}{140}$

$\frac{11}{14} > \frac{15}{28} > \frac{13}{35} > \frac{2}{7}$
