#### M3N.5: Students will understand the meaning of decimal fractions and common fractions in simple cases and apply them in problem-solving situations.

M3N.5.a: Understand a decimal fraction (i.e., 0.1) and a common fraction (i.e., 1/10) represent parts of a whole.

M3N.5.b: Understand the fraction a/b represents a equal sized parts of a whole that is divided into b equal sized parts.

M3N.5.c: Understand a one place decimal fraction represents tenths, i.e., 0.3 = 3/10.

M3N.5.d: Know and use decimal fractions and common fractions to represent the size of parts created by equal divisions of a whole.
