What is 60% written as a fraction? Be sure to reduce the fraction if necessary.
To write 60% as a fraction, we divide the percentage by 100 and simplify the fraction:
60% = 60/100
To reduce the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 20 in this case:
60/100 = (60 ÷ 20) / (100 ÷ 20) = 3/5
Therefore, 60% is equivalent to 3/5 as a fraction.
What is 22.5% written as a decimal?
To write 22.5% as a decimal, we divide the percentage by 100:
22.5% = 22.5/100
Dividing both the numerator and denominator by 10, we get:
22.5/100 = 2.25/10
Finally, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:
2.25/10 = (2.25 ÷ 2) / (10 ÷ 2) = 1.125 / 5
Therefore, 22.5% is equivalent to 0.225 as a decimal.
