1. 4 divided by 5 is 0.8. The percentage is 0.8*100%, or 80%.
2. 12.5% = 0.125, which is 1/8.
3. The probably of drawing a nine from a standard deck of cards on the second try is 3/51 if you took out a nine on the first try, and 4/51 if you didn't.
4. If Q=7, R = 61. If Q=9, R = 93.
5. 38/494=1/13; 16/320=1/20.

1) The decimal is 0.8, the percent is 80%
2) 1/8, or 2/16, or 3/24, or...
3) If you draw a nine on the first it's 3/51. If you don't it's 4/51.
4) If Q=7, R=49+12=61. If Q=9, R=81+12=93
5) 38/494=19/247 (lowest terms) = 0.0769
16/320 = 1/20 (lowest terms) = 0.05

3. if you didnt draw on the first time 1 in 13 if you did draw on then the probability is 1 in 17
4. R can = either 61 or 93
5. How is math supposed to prove that you are smart? you could say math test?

4/5 is .8 or 80%
12.5% is .125
Drew one:3/51
Didn't draw one:4/51
[both assuming you don't replace them]
if q=7, r=61
if q=9, r=93
38/494=19/245=0.077551020408163265306122448979592
16/320=1/20=5/100=.05
