45
It is: 81/3 = 27
1215/27 = 45
It is: 160 times 2 = 320
12 x 10
5 x 25
12.5 x 8 = 100
0.7 x 7 = 4.9
All multiples of the lowest common multiple of 15 and 27 are in both their times tables. The lcm of 15 and 27 is 135, so all multiples of 135 are in both the 15 and 27 times tables: 135, 270, 405, 540, 675, 810, 945, 1080, 1215, 1350, ...
3 times of 2025 is 3 * 2025 equalls 6075
circumference, 2 * pi * r equalls 150.72 r equalls 150.72 * 7 / 2 * 22 equalls 23.97cm r equalls 23.97cm
1, 3, 5, 9, 15, 27, 45, 81, 135, 243, 405, 1215.
81 x 3 = 243 is just one of many answers.
