Covert 3.92 into a mixed number in simplest from
Kobotan [32]
First, take three off it, because that will form the whole-number part:
3.92 = 3 + 0.92

Next, read off the place value of the last digit. The 2 is in the 'hundredths' column, which means that 0.92 = 92/100:
3.92 = 3 + 92/100

Finally, simplify 92/100 by dividing top and bottom by 4 to get 23/25. Then, shove it all together:
3.92 = 3 23/25

MaRussiya [10]
Mate, stop repeating questions, wait until your question has been answered.


15% of 180 is (180 * 0.15) = 27.

180 - 27 = $153 paid.


20% of 200 = (200 * 0.2) = 40.

200 - 40 = $160 paid.


Therefore Sport City offered the better deal.
