45*2 = 90 so 45*20 = 900
45*3 = 135
So 45*23 = 45*20 + 45*3 = 900 + 135 = 1035
1x3=3x3=9
How can you use 2x10 to find 4x10
1 x 7 plus 2 x 7 is the same as 3 x 7
The fact that 3 x 9 = 27
In what situtation can you use only multiplication to find equivalent fraction? Give an example
1x3=3x3=9
How can you use 2x10 to find 4x10
you can use multiplication facts to find division facts by dividing your divisor and your quotient to find your answer.
each side is multiplied together.

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.)
Yes - double, then double and then double again is the same as multiplying by 8.

1 x 7 plus 2 x 7 is the same as 3 x 7
To use "4s facts" (multiplication facts related to the number 4) to find "X," you can set up equations based on these facts. For instance, if you know that 4 times a certain number equals X, you can express this as 4n = X, where n is the number you are multiplying. By substituting known values into the equation or using division (X ÷ 4 = n), you can solve for X effectively. Additionally, using the properties of multiplication, you can explore different combinations that yield X.
Multiplication factors cannot be used to find divination factors.
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.
