Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this: Find the smallest multiple (LCM) of both numbers. Rewrite the fractions as equivalent fractions with the LCM as the denominator.

Karl had planned to drive for 1023 hours on a certain day during his road trip. When he became sleepy, however, he decided to de
netineya [11]

Since Karl became sleepy and decided to decrease his driving time by 25%, he drove <u>767.25 hours</u> that day.

<h3>What is driving time?</h3>

Planned driving time is the estimated time that Karl planned to drive between two points or to one's destination.

The Actual driving time is the actual time that it took Karl to drive from one point to his destination.

Driving time can be estimated or calculated by dividing the distance by the speed.

<h3>Data and Calculations:</h3>

The planned driving hours on a certain day = 1,023 hours

Decrease in driving time = 25%

Percentage of hours Karl drove = 75% (100 - 25)

Hours drove that day = 767.25 hours (1,023 x 75%)

Thus, Karl drove <u>767.25 hours</u> that day.

How many ways are there to assign six jobs to five different employees if every employee is assigned at least one job?
NARA [144]

Answer:

There are 1800 different ways.

Step-by-step explanation:

A permutation give as the total ways in which we can organized a group of elements where the order is important. So, the  permutation of n elements when all of them are not different is calculate as:

\frac{n!}{n1!n2!...nk!}

Where k is the number of elements that are different, n1, n2, ... nk are the number of times that very element appears and n is equal to n1+n2+...nk.

In this case we have 5 differents and general ways to assign six jobs to five different employees:

1. the first employee receive 2 jobs

2. the second employee receive 2 jobs

3. the third employee receive 2 jobs

4. the fourth employee receive 2 jobs

5. the fifth employee receive 2 jobs

Then, if the first employe receive 2 jobs, its mean that we have six people to permutate and the first person appears two times.

So the permutation of this 6 element in which one is repeat 2 times is calculate as:

\frac{6!}{2!*1!*1!*1!*1!*1!}=360

Therefore, there are 360 ways to organized five different employees into 6 jobs where the first person can receive two jobs.

For the other 4 options we can made the same calculation, so the total number of ways that we can organized five employees in six jobs are calculate as:

360*5=1800

Finally there are 1800 different ways.
