Document Summary
The rectangle below is 5/3 of a whole. Sketch a diagram to show 2/5 as some quantity of fifteenths. Sketch a diagram to show the improper fraction that is equivalent to 5 1/2. On the number line below, carefully plot 1/2, 2/5, 5/6, and 1/3. Each of these should fall on a tick mark (add tick marks as needed). Be sure it is clear how each is positioned relative to the endpoints and to its neighbors. Determine which of 13/40 and 14/41 is larger without using common denominators, decimals, or cross multiplication. Identify which properties of addition were used in the sequence of equivalent equations below. Write a word problem that fits the equation 4 ( 5) = n. do not change the subtraction to addition; write a word problem that fits one of the meanings of subtraction in a sensible way. 12 + (38 + 13) = (12 + 38) + 13 =
