Answer:
1/10
Explanation:
First, you must change the denominator of -2/5 to an even one. I changed it to 10 by multiplying the fraction by 2. Multiplying the fraction by 2 will give you -4/5. To add 1/2, find 1/2 of 10/10. 1/2 of 10/10 is 5/10, so add 5/10 to -4/10 and you get 1/10. Hope this helps. <3
