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.

It would be. 355 gigabytes because 3 gigabytes = 3000 megabytes so 3000 minus 2,645 = 355 megabytes and 355 megabytes as gigabytes =.355 gigabytes
