What is the value of p? p+1/5-1/2=1/10

First you get p on the side by itself p=1/10-1/5+1/2. Next you find a common denomenator which is 10 so p=1/10-2/10+5/10 and you get 4/10 which reduces to 2/5. To check this on a Ti-84 calculator store 2/5 for x and put x in the place of p and type in the equation and your answer will be 1/10

2/5 is the answer to this question because of distributive property. 1/10+1/2=3/5 Then, 3/5-1/5 is equal to 2/5.
