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(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27
27 times 15 is equal to 405
27
The number 81 appears in several times tables. Specifically, it is found in the 9 times table (9 x 9 = 81) and the 3 times table (3 x 27 = 81). Additionally, it can be expressed in the 1 times table (1 x 81 = 81).
The number at the midpoint of these two numbers is (15 + 27)/2 = 21
3 6 9 12 15 18 21 24 27 30 thats already up to 10 times. hope that helps
27*27 = 729
As the definition of a prime number is 'a number that can only be divided by one or itself, and still leave a whole number.' Anything in the eight times table would be divisible by two and four. 27 can also be divided by both three and nine.
I am guessing you want to know what number times 3 is 27. The answer is 9.
The 9 times table because 9*9 = 81 and 3*9 = 27
It is: 3*27 = 81
