Question

Arrange the the following in descending 7/15,11/21,1/7,17/35

Answer 1

Step-by-step explanation:

so easy first take LCM of denominator of all fraction then which is greater, smaller identify and then write in descending order

Answer 2

Answer:

$\underline { Descending \:order }$

$\frac{11}{21} < \frac{17}{35}<\frac{7}{15}<\frac{1}{7}$

Step-by-step explanation:

$Given \: rational \: numbers \: are \: \frac{7}{15},\:\frac{11}{21},\:\frac{1}{7},\:\frac{17}{35}$

$Find \: the \: LCM \: of \: denominators \: 15,\\21,7,35$

$LCM (15,21,7,35} = 105$

$\frac{7}{15} = \frac{ 7\times 7}{15\times 7} = \frac{49}{105}$

$\frac{11}{21} = \frac{ 11\times 5}{21\times 5} = \frac{55}{105}$

$\frac{1}{7} = \frac{ 1\times 15}{7\times 15} = \frac{15}{105}$

$\frac{17}{35} = \frac{ 17\times 3}{35\times 3} = \frac{51}{105}$

Therefore.,

$Arranging \:in \: descending \: order$

$\frac{55}{105},\: \frac{51}{105}, \frac{49}{105},\\\frac{15}{105}$

$\frac{11}{21} < \frac{17}{35}<\frac{7}{15}<\frac{1}{7}$
