Question 805925
That is the quantity {{{x}}} that out of 1200 is the same ratio or fraction as 40 out of 100.
{{{x/1200=40/100}}}
So, multiplying both sides times 1200, we get an equivalent equation:
{{{x=1200(40/100)}}}
No matter how you calculate it, the result is {{{highlight(480)}}}
You could calculate it as
{{{1200(40/100)=1200*0.4=480}}}
Or you could calculate it as
{{{1200*40/100)=(1200/100)*40=12*40=480}}}
 
In general, whatever the percentage it is, you can divide that by 100, and multiply times the result.
6% sales tax means the tax is {{{6/100}}} of the sales price.
That is {{{6/100=0.06}}} times the sales price.
It is $6 on a price of $100, and 6 cents on a price of 100 cents = $1.
You can multiply the price times 0.06 using a calculator.
