Question 903712
1/2% is equal to .5% is equal to .005


.86 is equal to .86


2/3 is equal to .66667 rounded to 5 decimal places.


.005 + .86 = .865 - .66667 = .198333


round that to 3 decimal places and you get .198.


you could also have converted them all to fractions as follows;


1/2% = 1/200


.86 = 86/100


2/3 = 2/3


the least common denominator appears to be 600, so translate all to common denominator of 600.


1/200 * 3/3 becomes 3/600


86/100 * 6/6 becomes 516/600


2/3 * 200/200 becomes 400/600


3/600 + 516/600 - 400/600 becomes equal to 119/600 which becomes equal to .198333... which rounds to .198 rounded to 3 decimal places.


you get the same answer either way so it's probably good.


the answer is .198.


note that the decimal equivalent of a percent is the percent divided by 100%.


100% / 100% = 1
50% / 100% = .5
5% / 100% = .05
.5% / 100% = .005
