Question

b. Suppose that you are downloading a movie with a file size of 2.8 GB (gigabyte). If the status bar above indicates how much of the movie has been downloaded, how many gigabytes have been downloaded so far?​

Answer 1

The size downloaded is an illustration of proportions.

The number of gigabytes downloaded is 2.1

The given parameters are:

$\mathbf{Size = 2.8GB}$

$\mathbf{Downloaded= 75\%}$ ---- the reading on the status bar.

So, the amount downloaded is calculated as:

$\mathbf{Amount = Downloaded \times Size}$

This gives

$\mathbf{Amount = 75\% \times 2.8GB}$

Multiply

$\mathbf{Amount = 2.1GB}$

Hence, the amount downloaded so far is 2.1GB
