Answer:
So, you will want to solve this as if you would any other addition problem.
8 + 4 = 12
We can asum that whatever the missing number is, it will add up to 15, which 12 plus 3 = 15 so
The missing number for the first row is 3!
Remember since that the answer was 15, then you carry the 1, so there will be a one in the second row too.
9 + 9 equals 18 plus 1 equals 19, and in the number in the answer has a 1 at the end so we can determine that:
The missing number in the second row, is 2!
Carry the 2 to the next row.
6 + 4 + 2 = 12, and the answer has a 9 in it, so: the answer would be 19, so
The missing number is 7.
Carry the 1.
Okay, so this one is tricky. The number has to be below 20, because there is a 1 in the answer, but the number in the answer is missing.
9 + 8 + 1 = 18. There is a missing number to, so in order for the number to be bellow 20, the only number that would make this a proportional would be:
The missing number in the problem is 1.
The missing number in the answer is 9!
The final answer is: 19,915!
