Question

if 5.25 MB have been downloaded and 2.25 MB are left. what percent of the application has already been downloaded?

Answer 1

5.25 + 2.25 = 7.50 MB

x/100 x (7.50) = 5.25
7.50x/100 = 5.25
7.50x = 5.25(100)
7.50x = 525
x = 525/7.50
x = 70
Hence, 70% of the application has already been downloaded. 

Answer 2

The percent of the application has already been downloaded will be $70\%.$

What is percentage?

Percentage is  a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

We have,

Downloaded application $=5.25$ MB

And,

Left to Download $=2.25$ MB

So,

Total size of application to be download $=5.25+2.25=7.50$ MB

Now,

Percent of the application downloaded $=\frac{Downloaded}{Total} *100$

                                                                  $=\frac{5.25}{7.50} *100$

Percent of the application downloaded $=70\%$

Hence we can say that the percent of the application has already been downloaded will be $70\%.$
