Interpret Fractions as Division
MGSE5.NF.3
Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
Example: 3/5 can be interpreted as “3 divided by 5 and as 3 shared by 5”.
