7. Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the
conclusions, e.g., by using the number line or another visual model. CA

7. Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit
fractions.1
a. Interpret division of a unit fraction by a non-zero whole number, and compute such quotients. For example, create
a story context for (1/3) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between
multiplication and division to explain that (1/3) ÷ 4 = 1/12 because (1/12) × 4 = 1/3.
b. Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context
for 4 ÷ (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and
division to explain that 4 ÷ (1/5) = 20 because 20 × (1/5) = 4.
c.Solve real-world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers
by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much
chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups
of raisins?
