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

Thank you I so had it wrong

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.

The question is .4% of 36

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

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

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

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

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.

hi, can you please work out one of the ratio ones like #5 or #13

7:25= 7/25

7/25=0.28

0.28=28% Because from decimal to percent you move your decimal over two places to the right.

I got perfect score, thanks for this practice Ilove Math ♥

wow its very helpfull thank you :>>>> !i!i!i!i!
