3 is 1 third of nine. so for 1x9 just do 1x3 and times the answer by 3. 1x3=3 and 3x3=9 so 1x9=9. 2x3=6 and 6x3=18 so 9x2=18 and so on and so on.

How can you use multiplication facts 1 and 2 to find 3 x 7?
The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc. For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)

How can you use multiplication facts about 3 to find multiplication facts about 9?
The multiplication facts for 3 is if you add all of the numerical values of the number given and that addition is divisible by three then your number is divisible by three. Ex. 738 add 7+3+8 that equals 18 18 is divisible by 3 therefore 738 is divisble by 3. 738/3 = 246 I know it sounds wierd but it always works. Now if this can be applied then it is divisble by 9 also. 738/9 = 82 I know its wierd. But math is wierd and its cool how it works like that.
