Rachel’s phone company limits her monthly data usage to 3 gigabytes. She has already used 2,645 megabytes. How many gigabytes of data does she have left this month?
There are 1,000 megabytes per every one gigabyte. So 3 gygabites times 1,000 is equal to 3,000 megabytes. So, 3,000 megabytes minus 2,645 megabytes is equal to 355 megabytes. She has 0.355 gigabytes left this month.
