The divisibility rule for 3 is add up the digits and check for divisibility. 7+2+4 = 13.13 is not evenly divisible by 3 so 724 is not divisibleby 3.
1, 2, 5, 10, 25, 50 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

You would say to yourself:-- If it has to be divisible by 5 and 9, then it's divisible by 45.-- The biggest 3-digit number is 999.-- 999 divided by 45 is 22.2-- So if I multiply 45 by only 22 and leave off the 0.2,I'll get the biggest one that's less than 999.-- 45 x 22 = 990 .
the next number will be 2 3 4 3 4 2 2 .............
216 is not prime. 216 = 2 * 2 * 2 * 3 * 3 * 3
The result of a number multiplied by itself
You would ahve to figure out the number.....For example: if the number was 3....3-2=1...that is the difference between 2 and 3
The number directly in the middle of 2 and -3 on the number line is -0.5.
x*2-3 = 2x - 3 ■
8/3 as a mixed number is 2 and 2/3
The number required is 2/3 because 3*(2/3)+2*(3/2) = 5
