*A reminder: A percent is basically a fraction whose denominator is 100. So, 34% is 34/100 and 98% is 98/100.*
So, to convert 3/4 to a percent, make it into a fraction whose denominator is 100. Find the number that you can multiply 4 by and get 100. That number is 100/4 = 25. So, multiply both the 3 and the 4 by 25, and it results in 75/100, which is 75%.
You can use any calculator to find the answer too. Type 3/4 into a calculator and it will say 0.75, and to make that a percentage multiply it by 100 => 75%.
