The percent of books did Johnny read that were for social studies=10%

Step-by-step explanation:

Given: Total books he read -= 20

Number of books for social studies = 2

The percent of books did Johnny read that were for social studies

$=\dfrac{\text{Number of social studies books}}{\text{Total books}}\times100\\\\=\dfrac{2}{20}\times100\%\\\\=\dfrac{100}{10}\%=10\%$

Hence, the percent of books did Johnny read that were for social studies=10%
