Adding and Subtracting Fractions

Exlpanation:

Step 1: First find the common denominator of the fractions

Step 2: Multiply the numbers that are in the common denominator to be the same

Step 3: Add or Subtract the numerator and the denominator to get the proper or improper answer

Step 4:Simplify the proper fraction until it can't be simplified anymore

Step 5: : Make sure your answer is in its simplest form

Step 6:You can add to see if you got your answer correct in subtraction

Multiplying and Dividing Fractions

Explanation: Multiplying Fractions

Step 1: First simplify in the begining if you can

Step 2: Multiply the fractions to get your answer

Step 3: If you simplified in the beginning just multiply it

Step 4: Divide the answer to get your answer [divide even more if it can be simplified more]

Step 5: Make sure your answer is in its simplest form

Steps for dividing fractions:

Step 1: Write the promblem to solve it

Step 2: When dividing fractions you need to remeber these key words:keep,change,flip

Step 3: First keep the first fraction

Step 4: Second change the divison sign into a multipulcation

Step 5: Third flip the second fraction

Step 6: Finally multiply the numbers and then divide to get your answer

Step 7: Make sure your answer is in the simpliest form

Multiplying decimals

Steps:

Step1:Write the numbers of the problem down.

Step2:When you write the numbers down you don't have to put the decimal exactly with the other number

Step3:After you put the decimal [that does not have to be in the same place]down for each number multiply normally

Step4:After you multiply the numbers, then count the decimal spaces in the numbers in each problem

Step5:After finding how many decimal places they are add up the total of the decimals

Step6:After finding the total of decimals in the problem then count the decimal spaces from the ones place until the decimal stops

Dividing decimals

Steps

Step1:First write the problem down

Step2:Then move the decimal point to the right

Step3:After moving the decimal to the right, then divide the problem

Step4:Make sure that you divide correctly

Step5:Finally when you get your answer you can check your answer by creating a multiplication problem

Adding and Subtracting Decimals

Adding Steps

Step 1: First write the problem down

Step 2: Then put the decimal exactly with the other number with the decimal

Step 3: Make sure you put the decimal in the correct spot because if you don't put it in the answer will be wrong

Step 4:After putting the decimal in the correct place then start to add the numbers up to get your answer to the problem

Step 5:After you found your answer to the problem, then bring the decimal down to the answer

Subtracting Steps

Step 1:First write the problem down

Step 2: Then put the decimal exactly with the other number with the decimal

Step 3: Make sure you put the decimal in the correct spot because if you don't put it in the answer will be wrong

Step 4:After putting the decimal in the correct place then start to subtract the numbers up to get your answer to the problem

Step 5:After you found your answer to the problem, then bring the decimal down to the answer
