please explain how to use hundreds chart to answer this queston;WHAT % OF THE NUMBERS ARE MULTIPLES OF BOTH 2 AND 3? i have no idea how to work it out, thanks

to be divisible by 2 AND by 3, the number must be divisible by 6
number of multiples of 6 for the first 100 numbers
= 100/6 = 16
the first one is 6 , then 12, 18 , .... 96
percentage = 16/100 = 16%
