Complete: What divided by two equals nine.

In this question, we have to find the missing dividend. This is the number which we have to divide by two. What number divided by two is equal to nine? We know when we divide our missing number by two, the quotient or the result is nine. This means there are nine twos in the missing number. So, if we multiply two by nine, we’ll find the missing number. What is two times nine? One times two is two, two times two is four, three times two is six, four times two is eight, five times two is 10, six times two is 12, seven times two is 14, eight times two is 16, and nine times two is 18. Nine twos are 18.

So, the missing dividend is 18. 18 divided by two equals nine. We used our knowledge of the two times table to help. Two times nine is 18. So, 18 divided by two equals nine. The missing number is 18.
