The mathematical question 18 + 9 is 27 and the answer to 18 - 9 is 9.
9 and any two multiples of it. There are an infinite number of correct answers. For example: 9, 18, and 27.
1, 2, 3, 6, 9, 18, 27, 54
6 does not matter as 18 is a multiple (6 x 3 = 18) 9 does not matter as 18 is a multiple (9 x 2 = 18) the multlples of 18 are 36 54 72 90 108 126 and so on ... not one but two answers, either 72 or 90 . 72 = 18 x 4 = 9 x 8 = 6 x 12 90 = 18 x 5 = 9 x 10 = 6 x 15
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.
There are infinitely many possible answers. 2 and 0.9 multiplied together or 1.5 and 0.3 added together or 5400 divided by 3000 or 5.832 to the power (1/3)
The square root of 4 * the square root of 81 four possible combinations:-2 * -9-2 * 92 * -92 * 9and two possible answers-2 * 9 and 2 * -9 = -18-2* -9 and 2 * 9 = 18
9+9+9+9+9+9=18+18+18=32+18=56
9 itself is a multiple of 9 since 9x1= 9 and of course it is a factor alsosince 18, 27, and 36 do not work, the only other is 9x5=45So the answers are 9 and 45Nine and forty_give
Three numbers are : 3 9 and 1 * * * * * Oh dear! Those are numbers that divide into 9, not numbers that are divisible (not divisable, incidentally) by 9. Possible answers to the question are 18, 27 and 36
The GCF is 9.
18-9=9
