Question

put ascending and descending order 3/10 ,3/15 ,3/17 ,3/9 ,4/10, 7/90​

Answer 1

Answer:

/-15, -2/-5 , -3/10 , 17/30

Step-by-step explanation:

First we will take LCM of 15,5,10,30  

LCM of 15,5,10,30 = 30

Then , we will make all the denominators = 30

Answer after making denominators 30 is -9/30 , -14/30, 17/30 , -12/30

Ascending order of the rational numbers with 30 as a denominator will be -14/30 , -12/30 , -9/30 , 17/30

Final answer will be 7/-15 , -2/-5, -3/10 , 17/30

7/-15,-3/10,2/5,17/30

Step-by-step explanation:

Answer 2

Answer:

Ascending Order: 7/90 < 3/17 < 3/15 < 3/10 < 3/9 < 4/10

Descending Order: 4/10 > 3/9 > 3/10 > 3/15 > 3/17 > 7/90

Step-by-step explanation:

First, we need to convert the fractions into like fractions.

10 = 2 * 5

15 = 3 * 5

17 = 17

9 = 3 * 3

90 = 2 * 3 * 3 * 5

LCM = 2 * 3 * 3 * 5 * 17

= 1,530

$\frac{3}{10} = \frac{459}{1,530}$

$\frac{3}{15} = \frac{306}{1,530}$

$\frac{3}{17} = \frac{270}{1,530}$

$\frac{3}{9} = \frac{510}{1,530}$

$\frac{4}{10} = \frac{612}{1,530}$

$\frac{7}{90} = \frac{119}{1,530}$

Now, let us arrange these fractions.

Ascending Order: $\frac{119}{1,530} < \frac{270}{1,530} < \frac{306}{1,530} < \frac{459}{1,530} < \frac{510}{1,530} < \frac{612}{1,530}$

Descending Order: $\frac{612}{1,530} > \frac{519}{1,530} > \frac{459}{1,530} > \frac{306}{1,530} > \frac{270}{1,530} > \frac{119}{1,530}$

We can simplify this, as to:

Ascending Order: 7/90 < 3/17 < 3/15 < 3/10 < 3/9 < 4/10

Descending Order: 4/10 > 3/9 > 3/10 > 3/15 > 3/17 > 7/90
