To write 52/100 as a decimal, we need to divide 52 by 100. When dividing by a number that only has zeroes (with a 1 as the first digit to the left), we can just move the decimal point of the number as many times to the right as there are zeroes. In 100, there are 2 zeroes. Moving the decimal point in 52.0 once to the left, we get 5.2. Doing it a second time, we get 0.52, meaning that the answer to this question is 0.52.
