Fill in the blank with the missing
factor: Two times what times three equals 18.

In this question, we have to find
the missing factor. This part of our expression is
inside a pair of brackets. This tells us that we need to
multiply these two factors together first. So something multiplied by three
and then multiplied by two equals 18. Two multiplied by what equals
18. We know that two times nine is
18. So what do we need to multiply by
three to give us nine? Three times three is nine. So two times three times three
equals 18. Three times three is nine; two
times nine is 18. The missing factor is three.

Another way we could’ve found the
missing factor is to start with the numbers we already had. Two times three times what equals
18. First, we can multiply two by
three, which is six. Then all we need to think about is
what do we time six by to give us a product of 18. And we know that six times three is
18. It doesn’t matter how we group the
factors or the order in which we multiply them; the product doesn’t change. Two times three times three equals
18. Two times three times three equals
18. And three times three times two
equals 18. The missing factor is three.
