The same equal groups of 12 and 18 refer to their common multiples, which can be found using the least common multiple (LCM). The LCM of 12 and 18 is 36, meaning that 36 can be divided into equal groups of both 12 and 18. Specifically, 36 can be divided into 3 groups of 12 and 2 groups of 18.
12 x 18 = 216
1.5 x 12 = 18
x + 12 = 18 Therefore, x = 18 - 12 x = 6

To convert feet to inches, you multiply the number of feet by 12, since there are 12 inches in a foot. Therefore, 18 feet is equal to 18 x 12 = 216 inches.
12 / 18 is equal to 0.666667 or 2/3.
18 groups of 4
18 * 12 = 216
12 x 18 = 216
Well, honey, when you divide 72 into equal groups, you're basically asking how many groups you can split 72 things into without any leftovers. So, if you want each group to have the same number of things, you'd end up with 1 group of 72, 2 groups of 36, 3 groups of 24, 4 groups of 18, 6 groups of 12, 8 groups of 9, or 12 groups of 6. Math can be a real hoot when you break it down like that!
1.5 x 12 = 18
12/18 = 2/3

2 groups of 9 9 groups of 2 6 groups of 3 3 grouos of 6 1 group of 18 18 groups of 1
x + 12 = 18 Therefore, x = 18 - 12 x = 6
