20*2+1+3/9=7
need to add grouping symbols to make it true

(20*(2+1)+3)/9 = 7

Step-by-step explanation:

You can tell that the only way that it can be true is using the division.

63/9 = 7

So I tried to find a way for everything before the grouping symbol to be 63:

(20*(2+1)+3)/9 = 7

7. d. 64

8. i. 32

9. c. 125

11. d. 81

12. i. 216

13. e. none of the above

14. g. 240

15. e. none of the above

16. g. 32

17.   e. none of the above
