This is how I"ve taught changing decimals into fractions. Remember: one space=10ths= /10 two spaces=100ths= /100 three spaces=1000= /1000 So: Take 2.72 from above. Everything to the left of the decimal is a whole number. Everything to the right ot the decimal goes on top of your fraction (the numerator). You use the amount of spaces filled to the right of the decimal to see if your denominator (the bottom of the fraction) is a 10, 100, 1000, or so on. On the decimal here, there are two spaces to the right of the decimal so your answer would be: 2 72/100 or 72 2---- 100 On 0.692 you have no whole number and three spaces to the right so it is 692 ----- 1000 Another easy way to remember is that you need a zero for every space to the right of the decimal. Three spaces=three zeros=1000. Hope this helps! Julie
