In multiplying by three, each row
is three more than the previous one. One times three equals three, two
times three equals six, three times three equals nine. Complete the following: Four times
three equals what. Complete the following: Five times
three equals what.

This question is all about
multiplying by three. We’re shown some models and told
that each row is three more than the previous one. One times three is three, two times
three is six, and three times three is nine. We have to complete four times
three and five times three.

We already know that one times
three is three, two times three is six, and three times three is nine. So, four times three is three more
than nine. Four times three is 12. And we know that five times three
is three more than 12. Three more than 12 is 15. So, five multiplied by three equals
15. The missing numbers are 12 and
15. Four times three equals 12, and
five times three equals 15.
