18. Let me show you why:
If I have 1 set of 9, I have 9
. . . . . . . . .
2 sets of 9 makes 18
. . . . . . . . . . . . . . . . . .
You can multiply 2 and 9 to get 18. Alternatively, you can multiply 3 and 6 to get 18 as well.
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
How about: 2*4.5 = 9 or 4*2.25 = 9
You can make 24 using the numbers 2, 2, 9, and 6 by the following calculation: (9 - 6) × 2 × 2. First, subtract 6 from 9 to get 3, then multiply that by 2 to get 6, and finally multiply by the other 2 to reach 24.

1/2 x 9
You can multiply 2 and 9 to get 18. Alternatively, you can multiply 3 and 6 to get 18 as well.
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
2/9 of 36= 8 To find the answer to this you should divide 36 by the denominator and multiply by the numerator. So: 36 divided by 9 and then multiply by 2 36/9= 4 4*2= 8
How about: 2*4.5 = 9 or 4*2.25 = 9
You can make 24 using the numbers 2, 2, 9, and 6 by the following calculation: (9 - 6) × 2 × 2. First, subtract 6 from 9 to get 3, then multiply that by 2 to get 6, and finally multiply by the other 2 to reach 24.

Multiply by 10/9 = 1.111...
1-9
Multiply the answer to the problem by the number that you are dividing by. (e.g. 18/2=9 Check it with 9*2=18)
The two numbers that add to get -2 and multiply to get 9 are -3 and -3. When you add -3 and -3, you get -6, and when you multiply them, you get 9. This is because -3 + -3 = -6 and -3 * -3 = 9.
