So it went from 30 to 35, or 5 bucks, if we take 30 to be the 100%, what is 5 off of it in percentage?
If the 3 numbers are in the ratio of 1:3:5, then all together,
they make (1 + 3 + 5) = 9 parts.
Since 72 has been split up into 9 parts, each part is (72 / 9) = 8 .
So the numbers are
1 part . . . . 1 x 8 = <em>8</em>
3 parts . . . 3 x 8 = <em>24</em>
5 parts . . . 5 x 8 = <em>40</em>
<u>Check:</u>
8 / 8 = 1
24/8 = 3
40/8 = 5
8 + 24 + 40 = 72 yay !
and a shout-out to Silversoul, who has so graciously
given me so many chances to fix my typos.

<span>do you mean which digit is added to 371 so that it is divisible by 3 </span>
<span>test for 3, sum of digits divisible by 3 </span>
<span>3 + 7 + 1 = 11 </span>
<span>if you add 3, 11 + 3 = 14 not divisible by 3 </span>
<span>if you add 7, 11+ 7 = 18 divisible by 3 </span>
<span>if you add 1, 11+ 1 = 12 divisible by 3 </span>
<span>if you add 1, 4, 7 divisible by 3 </span>
