Answer:
1/2
Step-by-step explanation:
To solve this, you have to do the inverse operation thing, so our equation is:
1/5 + 3/10 = 1/2
So 1/2 - 3/10 = 1/5
If you give them all common denominators you get x-3/10=2/10 now all you have to do is add what you have together and you get 5/10.If you check your work you get: 5/10 - 3/10 = 2/10 and that is true! 5/10 is the same as 1/2! :)
