PLEASE HELP!!! You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can yo
ipn [44]

Answer:

1140 ways.

Step-by-step explanation:

The applicable formula is: (n +r - 1)C(r-1), where n is the number of identical items (the candies), and r is the possible number of recipients (the kids).

The 17 identical candies, can be distributed among the 4 children in :  

=(17 + 4 - 1)C(4–1) = 20C3 ways.

= 20!/((20–3)!*3!) ways.

= 20*19*18*17!/(17!*(3*2*1)) = 20*19*18/6 ways

= 20*19*3 ways.  

=1140 ways.

Some more fractions, with common denominators
kenny6666 [7]

Answer:

\frac{5}{6}-\frac{1}{9} = \frac{45}{54} -\frac{6}{54} = \frac{13}{18}

Step-by-step explanation:

An easy way to find a common denominator is to multiply the denominators against each other, like this:

(\frac{9}{9})\frac{5}{6}-\frac{1}{9} (\frac{6}{6})

Now, simplify:

\frac{45}{54}-\frac{6}{54}

Then, subtract:

\frac{39}{54}

Simplify:

\frac{13}{18}      (Divide numerator and denominator by 3)

Hope this helps!!
