Let's evaluate each option to see which one makes the statement true.
-
12 + (6 x 11) - 7
= 12 + 66 - 7
= 12 + 66 = 78
= 78 - 7 = 71 (this is not equal to 72) -
12 + 6 x (11 - 7)
= 12 + 6 x 4
= 12 + 24 = 36 (this is not equal to 72) -
(12 + 6) x 11 - 7
= 18 x 11 - 7
= 198 - 7 = 191 (this is not equal to 72) -
(12 + 6) x (11 - 7)
= 18 x 4
= 72 (this is equal to 72)
The correct option that makes the statement true is (12 + 6) x (11 - 7) = 72.
