If you would like to solve 1/4 * 4/7, you can do this using the following steps:
<span>1/4 * 4/7 = (1 * 4) / (4 * 7) = 4/28 = 1/7
</span>
The correct result would be 1/7.
the total number of out comes would be 16^2 or 256.
some extra things...
A numbered card from 1 - 10 would be 1 over 10 or 10% chance of picking correctly.
a number cube from 1 - 6 would be 1 over 6 or 16.66% chance of picking correctly.
if you want to combine these and pick one from both, it becomes 1 over 16 or 6.25% chance of picking both correctly.

Answer:
3 pairs for the price of two.
Step-by-step explanation:
$10 per pair
then:
3 pairs costs $20
20/3 = $6.6667 each pair
- Buy one and get 25% of the second
25% = 25/100 = 0.25
then:
first pair $10
second pair: 10 - (10*0.25) = 10 - 2.5 = $7.5
first + second pair = 10 + 7.5 = 17.5
2 pairs costs $17.5
17.5/2 = $8.75 each pair
then:
the best deal:
3 pairs for the price of two.
