This week we went over decimals and rational numbers and how to do basic operations with decimals, like adding, subtraction, multiplying, and dividing. Basically rational numbers is just any number that can be put in a fraction. Adding decimals is easy all you have to do is line up the decimal points and add straight down like you normally would but remember to keep the decimals lined up. Subtraction is done the same way but remember to fill in the blanks with zeros that can help. Multiplying is pretty easy too all you have to do is line up the numbers multiply normally then count how many spots the decimal point was in each number and add that many to the solution. For example 2.33 x 2.4 = 3 spots so take the solution 5592 and move 3 spots = 5.592. Division is where I have trouble, first just ignore the decimal points and long divide like normal. What you have to remember is to put the decimal point in the same spot as the dividend.
Here is a few reminders of how to convert fractions to decimals and decimals to fractions
