.3 x 23 = 6.9
30% is .3 and you just multiply that by the total amount.
Or you can take 10% of it and multiply that value by 3.
Because 10% of 23 is 2.3 Just move the decimal over one. Then mulitple 2.3 by 3 and you get 6.9 again.
0.30 x 23 =$6.90 cents
10% = $2.30
20% = $4.60
30% = $6.90
i like persentage questions!
so let;s say $23 is 100%
then X$ is 30% and doing proportional equation like X=23x30/100=6.9$
so easy and think easy!
