Answer 2

Answer:

(1) 5/6 > 5/8 > 7/12 > 1/2 > 1/4

(2) 7/10 > 13/20 > 3/5 > 11/40

(3) 5/7 > 4/9 > 11/63 > 1/21

Step-by-step explanation:

Q1. LCM of denominators = 24

$\frac{1}{4}$ × $\frac{6}{6} = \frac{6}{24}$

$\frac{5}{6}$ × $\frac{4}{4} = \frac{20}{24}$

$\frac{5}{8}$ × $\frac{3}{3} = \frac{15}{24}$

$\frac{7}{12}$ × $\frac{2}{2} = \frac{14}{24}$

$\frac{1}{2}$ × $\frac{12}{12} = \frac{12}{24}$

Hence, descending order is 5/6 > 5/8 > 7/12 > 1/2 > 1/4

Q2. LCM of denominators = 40

$\frac{3}{5}$ × $\frac{8}{8} =\frac{24}{40}$

$\frac{7}{10}$ × $\frac{4}{4} = \frac{28}{40}$

$\frac{13}{20}$ × $\frac{2}{2} =\frac{26}{40}$

$\frac{11}{40}$ × $\frac{1}{1} = \frac{11}{40}$

Hence, the descending order is 7/10 > 13/20 > 3/5 > 11/40

Q3. LCM of denominators = 63

$\frac{4}{9}$ × $\frac{7}{7} = \frac{28}{63}$

$\frac{1}{21}$ × $\frac{3}{3} =\frac{3}{63}$

$\frac{5}{7}$ × $\frac{9}{9} =\frac{45}{63}$

$\frac{11}{63}$ × $\frac{1}{1} = \frac{11}{63}$

Hence, the descending order is 5/7 > 4/9 > 11/63 > 1/21
