Fractions

Add and subtract fractions

Step 1: first you must find a common denominator
Step 2: then you add or subtract (based on what you are doing)
Step 3: and then you simplify

Multiplication

Step 1: An easy way is to multiply across witch is when you multiply the numerators like they are their own problem and do the same for the denominators.
Step 2: Next you get the answers from the numerator and denominator and stack them (the numerator answer on top and the denominators answer on bottom)
Step 3: next you simplify witch is dividing it as small as you can until you can't anymore.
Step 4: if it is a improper fraction then you make it a mixed number (an improper fraction is when the top number the numerator is higher than the bottom number the denominator) you change a improper fraction to a mixed number is you see how many times the numerator goes into the denominator, then you take the number of times it goes into the denominator to the left of the fraction. You make the fraction with the same denominator and what did not go into your number to the left of the fraction.

Division

Step 1: an easy tip is to make it a multiplication problem when you flip the second fraction (you make the numerator the denominator and the denominator the numerator)
Step 2: next you cross multiply like I explained in the last section (multiplication)
Step 3: Then you get your answer and simplify.
Step 4: once again if you have a improper fraction then you turn it into a mixed number.

Dividing Decimals

Step 1: make your division problem
Step 2: make your divisor whole (what you are dividing by). to make it whole move it over.
Step 3: what we do to the divisor we need to do to the divieden (what you are dividing). So move the decimal point over as many times as you did to the divisor.
Step 4: now you just do normal division
Step 5: after you have your quotient add the decimal point.
