Sunita has a number of files of different sizes. In this context, which of the following statements are true?

Statements 2 and 3 are true because 250 bytes is smaller than half a megabyte and 50 gigabytes is larger than 100 megabytes.

Statement 1 is false because 47 kilobytes is far smaller than 10 megabytes, not larger.

Statement 2 is true because half a megabyte is about 500 kilobytes, dwarfing a mere 250 bytes.

Statement 3 is true because 50 gigabytes equals about 50000 megabytes, well above 100 megabytes.

Statement 4 is false because one terabyte is about 1000 gigabytes, far larger than 4 gigabytes.

Comparing sizes fairly means expressing each quantity in the same unit first.
