What operation should be used if a problem asks you to find the difference?
subtraction
How do you subtract fractions in simplest form?
You first need to find a common denominator, not necessarily the least common denominator. Next, you rename the fractions according to the common denominator. Only then can you subtract the fractions. After subtraction you should simplify the answer.
When given a problem with decimals and fractions should you convert them to all decimals or all fractions?
It really doesn't matter whichever one you are more comfortable with. fractions are a bit more challenging to convert.
What do i do with the remainders when dealing with fractions?
You should not have any remainders in fractions!

How many significant figures should be retained when performing addition and subtraction operations involving measurements with different numbers of significant figures?
When performing addition and subtraction operations with measurements of different significant figures, the result should be rounded to the same number of decimal places as the measurement with the fewest significant figures.

It really doesn't matter whichever one you are more comfortable with. fractions are a bit more challenging to convert.
Should all improper fractions be converted to mixed fractions?
Yes they should
When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.

You should not have any remainders in fractions!
When writing 1 as a fraction in a subtraction problem how do you know what the numerator and denominator should be?
It does not matter what they are as long as both are the same. 1 = 2/2 = 17/17 = 958/958 and so on.
When should you use PIMDAS in math?
Well, darling, you should use PEMDAS (not PIMDAS) when you want to solve mathematical expressions with multiple operations. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). So, next time you see a math problem, just remember PEMDAS and you'll be good to go!
Why should you keep your attention focused on your work when solve addition and subtraction problems?
You should keep your attention focused on your work at all times - not just when working with addition or subtraction!
