The answer is 70 (30 / 0.5 = 60, 60 + 10 = 70)
30 divided by 1/2 is 60.
Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5
Half is the same thing as .5 so you divide 30 by .5 and you get 60 then you add 10 so it is 70. TADA!!!
The answer is: 20/2 plus 30 = 40

30/0.5=60 60+10=70

(30 / 2) + 7 = 15 + 7 = 22
