3. count from: a. two tenths to four tenths. b. one twentieth to nine twentieths. c. four fifteenths to ten fifteenths. d. one hundredth to eight hundredths. e. ten fiftieths to twelve fiftieths.

Let's dive into the counting fun! For two tenths to four tenths, you would have: 0.2, 0.3, 0.4. Moving on to one twentieth to nine twentieths, we'd count: 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45. Now, from four fifteenths to ten fifteenths, you can count: 0.267 (4/15), 0.333 (5/15), 0.400 (6/15), 0.467 (7/15), 0.533 (8/15), 0.600 (9/15), and 0.667 (10/15). Moving to one hundredth to eight hundredths, we have: 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08. Lastly, from ten fiftieths to twelve fiftieths, we can say: 0.20, 0.22, 0.24. All together, it’s like a little math party! 🎉
