Best Answer:
7.8
Whats an irrational number again?
Answer: 5 (estimate)
Step-by-step explanation:
x - 17 4/5 = -13 1/5
Estimate: x - 18 = -13
x - 18 + 18 = -13 + 18
x = 5
actual answer without estimating using exact numbers is 4 3/5 (so estimate is reasonable)
Simple!
Since we can observe that they all have the same denominators (bottom part) we can just observe the numerator (top part)
6 is indeed greater than 5, yes? So we can safely say that
6/8 > 5/8
Now the for the second part.
6 is smaller than 7, yes? So we can make the observation that
6/8 < 7/8
Hope that makes sense! (Be sure to thank me, plz)
P.S. If you want an example of unlike denominators, let me know. <span />
Answer:
hours is closest to 2 hours.
Step-by-step explanation:
We have been given three numbers and we need to decide which of the three numbers is closest to 2.
In order to decide that, we will convert each of the given numbers into decimals and then we will compare.

Upon comparing 2.750, 2.375 and 2.600 we know that 2.375 is closest to 2. Therefore, out of the given three numbers,
is closest to 2.
