It is 1 that is the number you're looking for.
They both go into 1440, for example.
to answer this we can either divide by the divisor in each and compare the decimals, or do it the fractions way. Convert the bottom number in each to the same number (do the same to the top also). See below for the worked example: Find a number that 9 and 11 go into equally. The lowest is 99 (gotten from multiplying 9x11). Then as there are 11 9's in 99, you multiply 4 by 11, which is 44. as there are 9 11's in 99, you multiply 5 by 9 4/9 becomes 44 over 99. 5/11 becomes 45. Therefore 5/11 is slightly greater than 4/9
9/4 is equal to the mixed number 2 1/4
40/9 = (36+4)/9 = 36/9 + 4/9 = 4 + 4/9 or 44/9
63
Any number of the form 36*k where k is an integer.
225 and all its multiples.
Yes.
They can go into 8*4*9 = 288. That is not the smallest such number, but that was not the question.
yes ; 4+6+7=17 (3 and 9 can't go into 17 equally)

there are several but i know 3,240 is one.
You know that it is a multiple of 9 if it divides into 9 equally.
They both go into 1440, for example.
1, 2, 3, 4, 6, 9, 12, 18, 36.
There is no such even number.
