Is this correct? If I'm mistaken, please correct it for me, and show me how. Thanks.

Question

[Fractions, Decimals, and Percents.]

33 & 1/3 of $90 = $21.00
100% of 500 = $500
1% of 500 = $5.00
50% of 70 = $35.00
100% of 70 = $70.00

Thanks, you don't have to tell me all of then, just say some if they are correct/wrong.

Answer 1

33 & 1/3 of $90 = $21.00 -- Wrong
100% of 500 = $500 -- Right
1% of 500 = $5.00 -- Right
50% of 70 = $35.00 -- Right
100% of 70 = $70.00 -- Right

Answer 2

Could you explain why I got that one wrong?

Also, 66 1/2% of $24.00, how do I do these problems? :\

Thanks, by the way for checking them :)

Answer 3

For the 1st problem: 90*.333333

Answer 4

0.333333 * 90 = 29.999999

33 1/3% = 1/3
1/3 * 90 = 30
