We want to write the given fraction as a decimal number and a percent. 33/50Let's start by writing the fraction as a decimal. To do so, recall that 33 50 means 33Ă· 50. Therefore, we will divide the numerator by the denominator. Let's do it!
We found that 3350 written as a decimal is 0.66. Now let's use that to write the given fraction as a percent. To convert a decimal into a percentage, we multiply the decimal by 100 and add a percent sign. When multiplying a decimal by 100, we can think of this as moving the decimal point two digits to the right. Multiply by 100 & ⇒ 0.66* 100 = 66 Add Percent Sign & ⇒ 66 %
