Answer 1

As a fraction, the answer is 7/17

In decimal form that converts to approximately 0.41176 which is 41.176%

===============================================

Explanation:

We have 14 boys out of 14+20 = 34 students total

Divide the number of boys over the number of total students. Reduce the fraction as much as possible.

14/34 = (7*2)/(17*2) = 7/17

We can stop here if all your teacher wants is the fractional answer

-----

If you want the decimal form, you would use long division or a calculator to get this approximate result

7/17 = 0.41176

moving the decimal point over 2 spots to the right converts to percent form

0.41176 ---> 41.176%
