KATRIN_1 [288]

Answer:

Step-by-step explanation:

6/7 divided by 3/14 is 4.

Find common denominators.

6/7 would be changed into 12/14.

3/14 would stay the same because its denominator is already 14.

12/3 = 4

Therefore, 6/7 divided by 3/14 is 4.

how many different combinations of six people can sit in four chairs? assume one person sits in each chair

Tems11 [23]

We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called <em>six choose four</em>.

The following formula:

$_rC_n=\frac{n!}{r!(n-r)!}$

Is the combination of $r$ objects choosen from a total of $n$ . It's $n$ choose $r$ .

For our problem, we just need to compute the following:

$_4C_6=\frac{6!}{4!(6-4)!}=\frac{6\times5\times4!}{4!2!} =\frac{6\times5}{2\times1} =15$

Thus

$\boxed{_4C_6=15}$

Therefore the answer is 15 different combinations
