So basically, you have to find the decimal that equals 1/2 and the fraction that equals 0.48, but it has to be in simplest form. If you divide 1 by 2, you get 0.5, which would be the answer to 1/2=. For 0.48=, you would start by putting 48 over 100 because if you read the decimal aloud, it is 48 hundredths and 0.48 goes to the hundredths place. Then, you would begin to simplify 48/100. A common divisor for those 2 numbers is 2, but you could also use 4. I am going to use 4, so 48/100=12/25. Now that you have the fraction 12/25, look to see if there are any common factors. There are none, so 0.48=12/25.
Hope this helps!! :)
