Answer:

Step-by-step explanation:
We first let 0.38 (8 being repeated) be T.
Since z is recurring in 1 decimal places, we multiply it by 10. 10z = 3.88
Next, we subtract them. 10 r T 3.88 0.38 9x 3.5
Lastly, we divide both sides by 9 to get IC as a fraction. 3.5 T 9 35 90 7 18
Answer:
We end up with our original number
Step-by-step explanation:
Let x be our number
We increase by 100
increase = old number * 100%
increase = x*1
increase = x
New number = old number + increase
= x+x
=2x
Now we decrease by 50%
decrease = number *50%
= 2x*.5
=x
Final number = new number - decrease
= 2x-x
=x
Answer:1/20
Step-by-step explanation:
1/2=10/20
1/5=4/20 1/4=5/20
4/20 + 5/20 = 9/20
10/20 - 9/20 = 1/20
