Question

Order the set of numbers from least to greatest

Answer 1

Answer:  Option 'b' is correct.

Step-by-step explanation:

Since we have given that

$\frac{11}{20},\frac{1}{2},0.51$

Now, we have to arrange the set of numbers from least to greatest.

So, for this we have to make the denominator same ,

$\frac{11\times 5}{20\times 5}=\frac{55}{100}$

Similarly,

$\frac{1\times 50}{2\times 50}=\frac{50}{100}$

Similarly,

$\frac{51}{100}$

Numbers In increasing order :

$\frac{50}{100},\frac{51}{100},\frac{55}{100}\\\\\frac{1}{2},0.51,\frac{11}{20}$

Hence, Option 'b' is correct.

Answer 2

11/20 = 55/100 = 0.55
1/2 = 50/100 = 0.50
0.51 

1/2. 11/20, 0.51  (least to greatest)

C is your answer

hope this helps
