The peculiar aspect of your question is those gaps between numbers; it is fairly simple to add 523 and 334, but you have 5 23 and 3 34; it is not clear what you are trying to say. Possilby you mean 5 x 23 and 3 x 34. But it's hard to be sure.
Exactly as in the question: 7+5 = 12
12 plus 9 equals 21.
To find out how many times 12 goes into 116, you can divide 116 by 12. This gives you approximately 9.67. Therefore, 12 goes into 116 a total of 9 times with a remainder, as 12 multiplied by 9 equals 108, which is the largest multiple of 12 that is less than 116.

12 + 10 + 11 equals 33
12.
Exactly as in the question: 7+5 = 12
6+6=12, easy :D
19 plus 12 equals 31. This is because addition is a mathematical operation that combines two numbers to find their total sum. In this case, adding 19 and 12 together results in a sum of 31.
The sum of 7/15 and 5/12 equals 53/60
it equals 72. just do 12 X 6
it equals 70
12 plus 9 equals 21.
To find out how many times 12 goes into 116, you can divide 116 by 12. This gives you approximately 9.67. Therefore, 12 goes into 116 a total of 9 times with a remainder, as 12 multiplied by 9 equals 108, which is the largest multiple of 12 that is less than 116.
12+12
