The table shows the webster family’s monthly expenses for the first three months of the year. they are $2,687.44, $2,613.09, and $2,808.64. what is the average monthly expenditure for all expenses?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

What are the digits that repeat in the smallest sequence of repeating digits in the decimal equivalent of 24/11?
