Answer:

Step-by-step explanation:
6 • 1/3 = 18
18 • 1/2 = 36
36 - 6 = 30
Take the regular price, multiply it by .2, subtract that off of the regular price. What it means is 20% of the regular price is taken away from the regular price.
If the probability of getting heads is 1/2 and you flipped a coin 200 times you would land on heads 100 times
Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.
Example: start with 2/3. Mult num. and den. both by 7: 14/21.
2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.
