Answer: 6
Step-by-step explanation:
If we call each team, A, B, C and D, each team has to play each other team once. Let's call each pairing between 2 teams the 2 teams' letters next to each other, e.g. AB is A playing against B. A has to play against B, C and D so we have AB, AC and AD. So we have 3 so far.
We have already counted that B is playing A but we haven't counted B playing C and D yet so we also have BC and BD. So we have 5 in total
Lastly, C needs to play D, we have already counted C playing B and C playing A so we have CD left. In total that gives 6.
Now we have already included D playing every other team so we don't include any other pairings.
In total, now every team has played every other team giving a total of 6.
(another way of solving this is doing "3!2 but if you haven't learnt factorials yet stick to the first method.
The greatest number of silverware holders Mary can stock is 4, each containing 4 forks and 3 knives so that no fork or knife is left over and are distributed equally.
What is distribution?
When a quantity is to be distributed equally into a certain number of groups, we divide the quantity by the number of groups.
Solution:
Given: 16 Forks and 12 knives
To find: number of silverware stocks = ?
As we know that the knives and forks should be distributed equally in each silverware holder, 4 forks and 3 knives will go into each of the silverware holder.
Now, we need number of silverware holders each having same number of forks and knives.
4 forks×4 = 16
3 knives× 4 = 12
∴ Number of silverware holders Mary requires to distribute knives and forks equally with no left over is 4.
