This module is from Fundamentals of Mathematics by Denny Burzynski and Wade Ellis, Jr. This module discusses how to add and subtract mixed numbers. By the end of the module students should be able to add and subtract mixed numbers.
Section overview
The Method of Converting to Improper Fractions
To add or subtract mixed numbers, convert each mixed number to an improper fraction, then add or subtract the resulting improper fractions.
Sample set a
Find the following sums and differences.
. Convert each mixed number to an improper fraction.
Now add the improper fractions
.
The LCD = 20.
Thus,
.
. Convert the mixed number to an improper fraction.
The LCD = 24.
Thus,
.
Practice set a
Find the following sums and differences.
Exercises
For the following problems, perform each indicated operation.

Think about the wording.
A particular computer stock opened at

. What was the net gain for this stock?
A particular diet program claims that
pounds can be lost the first month,
pounds can be lost the second month, and
pounds can be lost the third month. How many pounds does this diet program claim a person can lose over a 3-month period?
If a person who weighs
pounds goes on the diet program described in the problem above, how much would he weigh at the end of 3 months?
If the diet program described in the problem above makes the additional claim that from the fourth month on, a person will lose
pounds a month, how much will a person who begins the program weighing
pounds weight after 8 months?
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️
