Answer:
Flip the second number
Step-by-step explanation:
To divide by a fraction, you simply flip it over and multiply
Take # 7 as an example:
5 /
becomes 5 X ![\frac{6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B1%7D)
Of course to make a whole number you put a 1 under it:
5 becomes ![\frac{5}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B1%7D)
Then you multiply straight across (top X top and bottom X Bottom)
Lastly, simplify as needed:
2 / ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Make the two a fraction and flip the fraction you are dividing with:
![\frac{2}{1} X \frac{3}{1} = \frac{6}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1%7D%20X%20%5Cfrac%7B3%7D%7B1%7D%20%3D%20%5Cfrac%7B6%7D%7B1%7D)
which reduces to 6
To remember the steps use Keep it, Change it, Flip it.
Keep the first number, change from division to multiply, and flip the fraction you were going to divide by.

Mechanical Energy is the total energy of an object or group of objects due to large-scale motions and interactions. An example of that is when a basketball player shoots the ball.
Answer is (b) cause 13 x 2 is 26
Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:
![30\% \,\, \textrm{of} \,\,300 = \dfrac{3}{10} \cdot 300 = \dfrac{900}{10} = 90](https://tex.z-dn.net/?f=%2030%5C%25%20%5C%2C%5C%2C%20%5Ctextrm%7Bof%7D%20%5C%2C%5C%2C300%20%3D%20%5Cdfrac%7B3%7D%7B10%7D%20%5Ccdot%20300%20%3D%20%5Cdfrac%7B900%7D%7B10%7D%20%3D%2090%20)
Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)
Answer:
