To write 1/2 as a decimal, divide 1 by 2 to get 0.5. To write 1/2 as a percent, multiply 0.5 by 100 to get 50%.
Step-by-step explanation:
To write 1/2 as a decimal, you divide the numerator (1) by the denominator (2). So, 1 divided by 2 is 0.5. Therefore, 1/2 as a decimal is 0.5.
To write 1/2 as a percent, you multiply the decimal equivalent (0.5) by 100. So, 0.5 multiplied by 100 is 50. Therefore, 1/2 as a percent is 50%.
