Question

George had finished 3/4 of his science project. What percent of the project had he finished?

Answer 1

the easiest way to do questions like this is to think of it this way;

1/4 of 100 is 25, because 100/4 is 25. so 3/4 of 100 is 75, because 25*3 is 75.
This way works for me, but everyone thinks of math in different ways.

The answer is 75%

Answer 2

to change a fraction into a percentage, just multiply the fraction by 100%. so here we got 3/4 x 100% = 75 %
