Answers

1. Answer :

17/24, 5/12, 9/16

Convert all the fractions into like fractions.  

We can use LCM method to make the denominators of the fractions same. 

Here, the denominators are 24, 12 and 16.

LCM of (24, 12, 16) = 48

Now, make the denominators of all the fractions as 48 using multiplication. 

17/24 = (17 ⋅ 2)/(24 ⋅ 2) = 34/48

5/12 = (5 ⋅ 4)/(12 ⋅ 4) = 20/48

9/16 = (9 ⋅ 3)/(16 ⋅ 3) = 27/48

Now, compare the numerators of like fractions above and order them from least to greatest.

20/48, 27/48, 34/48

Substitute the corresponding original fractions.  

5/12, 9/16, 17/24

Therefore, the order of the given fractions from least to greatest is 

5/12, 9/16, 17/24

2. Answer :

0.1, 7/10, 0.3

Convert the decimal numbers 0.1 and 0.3 into fractions. 

0.1 = (0.1 ⋅ 10)/10 = 1/10

0.3 = (0.3 ⋅ 10)/10 = 3/10

Substitute 1/10 for 0.1 and 3/10 for 0.3 in the given list of values.

1/10, 7/10, 3/10

1/10, 7/10 and 3/10 are all like fractions. Because, all of them are having same denominator 10. 

Now, compare the numerators of the fractions 1/10, 7/10 and 3/10 and order them from greatest to least.

7/10, 3/10, 1/10

Substitute the corresponding original values.  

7/10, 0.3, 0.1

Therefore, the order of the given values from greatest to greatest is 

7/10, 0.3, 0.1

3. Answer :

3/4, 2/5, 0.125

Convert the decimal number 0.125 into a fraction. 

0.125 = (0.125 ⋅ 1000)/1000  

0.125 = 125/1000

0.125 = 1/8

Substitute 1/8 for 0.125 in the given list of values.

Then, we have

3/4, 2/5, 1/8

Convert all the fractions in step 2 to like fractions.  

We can use LCM method to make the denominators of the fractions same. 

Here, the denominators are 4, 5 and 8.

LCM of (4, 5, 8) = 40

Now, make the denominators of all the fractions as 40 using multiplication. 

3/4 = (3 ⋅ 10)/(4 ⋅ 10) = 30/40

2/5 = (2 ⋅ 8)/(5 ⋅ 8) = 16/40

0.125 = 1/8 = (1 ⋅ 5)/(8 ⋅ 5) = 5/40

Now, compare the numerators of like fractions above and order them from least to greatest.

5/40, 16/40, 30/40

Substitute the corresponding original values.  

0.125, 2/5, 3/4

Therefore, the order of the given values from least to greatest is 

0.125, 2/5, 3/4

4. Answer :

5/6, 0.375, 1/4

Convert the decimal number 0.375 into a fraction. 

0.375 = (0.375 ⋅ 1000)/1000

0.375 = 375/1000

0.375 = 3/8

Substitute 3/8 for 0.375 in the given list of values.

5/6, 3/8, 1/4

Convert all the fractions to like fractions.  

We can use LCM method to make the denominators of the fractions same. 

Here, the denominators are 6, 8 and 4.

LCM of (6, 8, 4) = 24

Now, make the denominators of all the fractions as 24 using multiplication. 

5/6 = (5 ⋅ 4)/(6 ⋅ 4) = 20/24

0.375 = 3/8 = (3 ⋅ 3)/(8 ⋅ 3) = 9/24

1/4 = (1 ⋅ 6)/(4 ⋅ 6) = 6/24

Now, compare the numerators of like fractions above and order them from least to greatest.

6/24, 9/24, 20/24

Substitute the corresponding original values.  

1/4, 0.375, 5/6

Therefore, the order of the given values from least to greatest is 

1/4, 0.375, 5/6

5. Answer :

1/20, 0.2, 0.074

Convert all the decimal numbers 0.2 and 0.074 into fractions. 

0.2 = (0.2 ⋅ 10)/10 = 2/10 = 1/5

0.074 = (0.074 ⋅ 1000)/1000 = 74/1000 = 37/500

Substitute 1/5 for 0.2 and 37/500 for 0.74 in the given list of values.

1/20, 1/5, 37/500

Convert all the fractions above to like fractions. 

We can use LCM method to make the denominators of the fractions same. 

Here, the denominators are 20, 5 and 500.

LCM of (20, 5, 500) = 500

Now, make the denominators of all the fractions as 500 using multiplication. 

1/20 = (1 ⋅ 25)/(20 ⋅ 25) = 25/500

0.2 = 1/5 = (1 ⋅ 100)/(5 ⋅ 100) = 100/500

0.074 = 37/500 = (37 ⋅ 1)/(500 ⋅ 1) = 37/500

Now, compare the numerators of like fractions above and order them from greatest to least.

100/500, 37/500, 25/500

Substitute the corresponding decimals.  

0.2, 0.074, 1/20

Therefore, the order of the given decimal numbers from least to greatest is 

0.2, 0.074, 1/20
