20 % are the math apps in total number of apps
Solution:
Maya downloaded some math and science apps from Google Play
The number of math apps is 25% of the number of science apps
Let "x" be the number of science apps
Then, we get,
Number of math apps = 25 % of number of science apps
Number of math apps = 25 % of x
[tex]\text{Number of math apps } = \frac{25}{100} \times x[/tex]
Number of math apps = 0.25x
What percent are the math apps to the total number of apps?
Total number of apps = x + 0.25x = 1.25x
Math apps = 0.25x
We have to find the percent of math apps in total number of apps
[tex]\text{ percent of math apps} = \frac{\text{Math app}}{\text{total number of apps}} \times 100[/tex]
[tex]\text{ percent of math apps} = \frac{0.25x}{1.25x} \times 100\\\\\text{ percent of math apps} = 0.2 \times 100\\\\\text{ percent of math apps} = 20[/tex]
Thus 20 % are the math apps in total number of apps
