What is a multiplication fact that can you double to find 4×7

you can use multiplication facts to find division facts by dividing your divisor and your quotient to find your answer.
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.)
A multiplication grid, or multiplication table, is used to find the product of two numbers quickly. To use it, locate one number along the top row and the other down the left column. Then, find the cell where the row and column intersect; this cell contains the product of the two numbers. This tool is particularly helpful for visualizing and memorizing multiplication facts.
Yes - double, then double and then double again is the same as multiplying by 8.
The fact that 3 x 9 = 27
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.
6.12,18,24,30,36 just go through the 3 multiplication facts and find the even ones and there's your answer.
