Answer:
s = 2/5
Explanation:
Add 1/5 to both sides
s - 1/5 = 2/10
+ 1/5 + 1/5
- 1/5 and + 1/5 cancels out
2/10 + 1/5 ---> 2/10 + 2/10 = 4/10
Simplify 4/10 by dividing by 2
4/10 = 2/5
4/10 or 2/5
(Make denominators equal)
S - 2/10 = 2/10
(Add 2/10 to both sides)
S = 2/10 + 2/10
s = 4/10
(Simplify by dividing by 2)
S = 2/5
