40/9 = (36+4)/9 = 36/9 + 4/9 = 4 + 4/9 or 44/9
4 and 4/9
-2 and 9/40
These numbers between 1 and 40 have an odd number of factors: 4, 9, 16, 25, 36.
easy, 40
Their lowest common factor is 360 . There are an infinite number of more examples.
40 if you divide 360 by 9 you get 40 and 40 time 9 equals 360
40/9 = (36+4)/9 = 36/9 + 4/9 = 4 + 4/9 or 44/9
0.025
4 and 4/9
31, 40 1st, 3rd, etc go up by 4, others by 9
40
