hello the answer would be 3/10. because when a math question has of in it, ("1/2 OF") means its multiplication most of the time so then you do 3/5 ÷ 1/2 YOU CAN CONVERT THE DIVISION SYMBOL by using KEEP CHANGE FLIP. and change the equation to 3/5 × 2/2 and get 6/10 and took 3/10 so 3/10 6/10=3/10. hope I could help
