How is 0.25 the decimal for 3 over 12?

Answer 1

3 over 12 or 3/12 can be simplified to 1 over 4 or 1/4 because both the numerator and denominator can be divided by three. .25 is said "twenty-five hundredths", or 25/100. If you divide the numerator and denominator by 25, you get 1/4. So, .25 is equivalent to 1/4 and 3/12 is equivalent to 1/4 so both are equivalent. Also, if you divide 3 by 12, you get .25.
