6 x 90 = 540
It's like this:
90
x 6
-------
540
6 goes into 90 15 times
15 × 6 = 90
6 goes into 90 exactly 15 times.
15 times 90 equals 1350.
pr(six) = 1/6 → expected 6s in 90 rolls = 1/6 × 90 = 15

15 times 6 = 90
6 with 6 remaining 90 - 6 = 84 = 14 x 6
The six times tables are any and all multiples of 6. Therefore, any numbers that divide evenly by 6 will be in the six times tables, and any that don't won't be. 90/6 = 15, and so 90 does divide evenly by 6. Thus, 90 is in the six times tables.
To determine how many times 15 goes into 90, you would divide 90 by 15. The result of this division is 6, meaning that 15 goes into 90 six times evenly. In mathematical terms, this can be expressed as 90 ÷ 15 = 6.
6 x 15 = 90
