How can you use 2x10 to find 4x10
if you do 3x7 and you need to get 6x7 then just do it 2 times
In what situtation can you use only multiplication to find equivalent fraction? Give an example
yes multiplication can help with division because if you find the answer to a multiplication problem use the answer to get the divison.Exanple:32divided by4=8=8x4=32
I think 7x3 is = to 21
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.
if you do 3x7 and you need to get 6x7 then just do it 2 times
2x7 = 14 x7 = 7 3x7 = 3*7 = 21
each side is multiplied together.
routine practice
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.
array
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.
