Explanation:
To use mental math to express 12/25 as a percent, you can follow these steps:
Understand that a percent is a fraction with a denominator of 100.
Think about how you can convert the fraction 12/25 to have a denominator of 100. Since 4 times 25 equals 100, multiply both the numerator and denominator by 4.
Now your fraction looks like (12×4)/(25×4), which simplifies to 48/100.
Since the fraction is now out of 100, it can easily be read as a percent. Therefore, 48/100 is 48%.
The phrase to remember is: “part over total, times one hundred, equals percent.” Here, the “part” is 12 and the “total” is 25, multiplying by 4 turns the total into 100, and the resulting part (48) is the percent value.
