Hey! this is very simple to learn. So 3/4 would be 75% just think of quarter (25,50,75,100) Then to convert a decimal to a percent you just multiply it by 100. When multiplying decimals by 100 you just move the decimal over two spaces. So .72 would be 72% and .63 would be 63%. Knowing all of this the answer is right there!
From least to greatest 0.63, 69%, 0.72, 3/4
I hope this helps!
