# Number Systems Fluency

• Find the greatest common factor of two whole numbers less than or equal to 100. • Find the least common multiple of two whole numbers less than or equal to 12. • Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. • Interpret and compute quotients of fractions. • Solve word problems involving division of fractions by fractions using visual fraction models and equations to represent the problem. • Fluently divide multi-digit numbers using the standard algorithm. • Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
