Hello there!
Here is a simple step you need to follow and remember it. You'll be able to find the percentage of any fraction next time.
First, start by transferring the fraction to decimal. To do that, divide the top number by the bottom.
74 ÷ 50 = 1.48
Second, multiply the decimal you got by 100
1.48 * 100 = 148%
Thus,
74/50 as a percentage is 148%
Good luck!
