It's 4/5....you just find out what each of the denominators are equal to....so they are both factors of 45......so you take the one with 2/5 and multiply by 9 on top and bottom and then take 2/9 and multiply it by 5 on top and bottom so you have 18/45 and 10/45....so now you take the to and add them up to get 28/45 and now you can simplify if necessary <span />

The square root of 81 repeating is 9.05, (Rounded)
<u>-It goes on forever.</u>
Since it goes on forever, it's not a whole number or a natural number, both kind of numbers never keep going on forever.
Which leaves us with Irrational and Real Numbers
Therefore, 1 and 2 is your answer.
Best of Luck to you.

Answer:45.9
Step-by-step explanation:
Circumference=12
Length of arc=8/5=1.6
π=3.14
Circumference=2 x π x r
12=2x3.14xr
12=6.28 x r
Divide both sides by 6.28
12/6.28=(6.28 x r)/6.28
2=r
r=2
Length of arc =Φ/360 x 2 x π x r
1.6=Φ/360 x 2 x 3.14 x 2
1.6=(Φ x 2 x 3.14 x2)/360
1.6=12.56Φ/360
Cross multiply
1.6x360=12.56Φ
576=12.56Φ
Divide both sides by 12.56
576/12.56=12.56Φ/12.56
45.9=Φ
Φ=45.9
