Question

Least to greatest..pls

Answer 1

The list that shows the numbers ordered from least to greatest is:

• A.
  `(√(2) )/(2), (\pi )/(4), 0.8, (5)/(6)`

Explanation:

To identify what is the least number or the greatest number in the list, first, we're gonna show all the numbers in their decimal form:

• 
  `(√(2))/(2)= 0.7071067812`
• 
  `(\pi)/(4)=0.7853981634`
• 
  `(5)/(6)= 0.8333333333`
• 
  `0.8 = 0.8`

Now, we must to identify the least number in the list, as you can see, it's 0.7071067812, more or less 0.71, by this reason
`(√(2))/(2)` must be the first number, the next number is 0.7853981634, more or less 0.79, so
`(\pi )/(4)` must be the second number, the third number can't be
`(5)/(6)` because 0.833333333 is greatest than 0.8, so the third number is 0.8 and the last number is
`(5)/(6)` in the ordered list from least to greatest, and the option give us that order is the A option.
