They dont. This is just so in school they can be taught easily.
No, 86 is not in the 4 times tables. The 4 times tables consist of multiples of 4, starting from 4, 8, 12, 16, and so on. Since 86 is not a multiple of 4, it is not found in the 4 times tables.
The smallest number that is in the 11, 12, and 13 times tables is the least common multiple (LCM) of these numbers. To find the LCM, we can calculate it as follows: LCM(11, 12, 13) = 11 × 12 × 13 = 1716. Therefore, the smallest number that is in the 11, 12, and 13 times tables is 1716.
12, 24, 36, 48, 60 . . .
They do not necessarily do so. It depends on the country and school. I learned them to 10 times but for tables up to 30!
If going up to 12 times, then 56 is in the 7 times and 8 times tables.
It consists of the multiples of 59, from 1 to 10 (or 12).
It consists of the multiples of 61, from 1 to 10 (or 12).
It consists of the multiples of 93, from 1 to 10 (or 12).
It consists of the multiples of 66, from 1 to 10 (or 12).
No, 99 is not in the 6 times tables. The multiples of 6 are 6, 12, 18, 24, and so on, increasing by 6 each time. Since 99 is not divisible by 6 without a remainder, it does not appear in the 6 times tables.
The answer is 48.
Exactly the same as the 12 times table - except each answer needs a zero at the end !
