.4% of 36 = .4/100 * 36 = (.4 *36)/100 = 14.4/100 = 0.144 The answer is correct

• August 11, 2017

Thank you I so had it wrong

• November 21, 2018

THIS WAS SO EASY

4% of 36 is 1.44 the decimal point was placed incorectly in front of 4. 4%to decimal is 0.04 if the decimal point is placed in front of 4 then 4 means 40% or .4 in decimal.

• December 18, 2017

The question is .4% of 36

• August 30, 2019

OOH!! I see the point now. that’s true you are correct sorry I don’t see the point before the 4

• March 1, 2018

Sooooo……….How would I Know to do the last step(14.4/100) to complete the problem?

• March 5, 2018

OK 14.4/100 – move decimal 2 places left – (dividing so the result will be smaller) = 0.144

• April 26, 2018

Thank you Brian for working that one out, it was very helpful.

• August 30, 2019

excuse me but I think you have a mistake because you forget to put a zero in the decimal 0.04 and you have 0.4 when we convert a percent to a decimal we move two place to the left and you move only one.
