to multiply a number by 9, the numbers in your answers add up to 9. Here's a pattern:
9*1=9 9+0=9
9*2=18 1+8=9
9*3=27 2+7=9.
When we get to 9*11, we get 99. 9+9=18, 1+8=9. The rule still applies to 99.
9 and 9
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
no
Multiply it by 0.09.
There are nine ones in the answer. 12345679 × 9 = 111111111
9 and 9
Multiply whatever number is on line 7 by 9.
If you multiply 2*9, you get 18. Multiply that by 10 to get a three digit number, and you get 180.
no
What you have to do is multiply that number by the same number for example 3x3=9 so 9 is a square number.
Multiply it by 0.09.
because you can multiply a number (in this case 3) by itself and get that number
Multiply the answer to the problem by the number that you are dividing by. (e.g. 18/2=9 Check it with 9*2=18)
Using algebra the number works out as 25
There are nine ones in the answer. 12345679 × 9 = 111111111
16.5
10989 * 9 = 98901
