Answer:
A: sqrt(11)
B: 4.2
C: sqrt(26)
Step-by-step explanation:
First, 4^2 = 16
That means that sqrt 11 is smaller than 4.2 (a value greater than 4). This is because sqrt16>sqrt11.
Sqrt(26) is greater than sqrt(25) = 5. That means that it's greater than 4.2. 
Hence, the order given above.

Numbers are 416, 417 and 418
<u>Step-by-step explanation:</u>
Step 1: 
Let the numbers be x, x + 1 and x + 2. Given that their sum is 1251.
⇒ x  + x + 1 + x + 2 = 1251
⇒ 3x + 3 = 1251
⇒ 3x = 1248
⇒ x = 416
Step 2: 
Find the other numbers.
⇒ x + 1 = 417 and x + 2 = 418
