Step-by-step explanation:
Step 1: Add the numbers.
20.25 can also be expressed as , because
=
=
. So if we add
and 11, we would get
Step 2: Solve
- Subtract the whole numbers
- Combine the fractions
This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.
LCM
Therefore, the simplified expression to this is .

We have been given that Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long. We are asked to find the length of chain of bacteria in centimeters.
We know that 1 millimeter is equal to 0.1 centimeter.
To convert 10 milllimeters into centimeters, we will multiply 10 by 0.1.
Therefore, the chain of the bacteria is 1 cm long.
