Which diagram a fraction equivalent to 75%

Hi there! The third answer is correct.

The third diagram has a total of 20 boxes. Of those boxed, 15 are coloured. We can express this as a fraction and to find our answer we only need to change this fraction into a decimal and multiply by 100.

Diagram C represents 75%.

In Diagram C, since there are 15 boxes filled out of 20 boxes, the fraction is . Simplify and express that fraction as a decimal. To turn a decimal into a percentage, mulitply the decimal by 100.
%

Another way to solve is to think of the diagram equal to 100%. In Diagram C, each box equals 5%. This would make all 20 boxes together equal 100%. Since 15 boxes were filled, and each box represents 5%, you can multiply 15 by 5.
15 x 5 = 75
