Mixed Number – a whole number and a fraction put together

5 1/2 3 3/4 19 5/3

Draw number line and label – 2 ¼ to 2 ¼. Plot points on number line and label them A, B, C, and D.

A =B =C =D = ___________________________________________________________________________________*Converting Improper Fractions to Mixed Numbers:

9/8 Divide 9 ÷ 8 = 1 1/8(Improper Fraction) (Mixed Number)___________________________________________________________________________________*Converting Mixed Numbers to Improper Fractions:

3 1/3 Multiply whole number & denominator. 7/3(Mixed Number) Add numerator. (Improper Fraction)___________________________________________________________________________________

*Subtracting a Mixed Number from a Whole Number. 3 – 1 1/4

Work the following examples:

Ex. 1 3 1/3 + 4 1/4 = (In simplest form)

Ex. 2 4 1/8 + 9 5/8 = (Must simplify answer)

Ex. 3 7 6/10 + 8 7/10 = (Must divide improper fraction)

Ex. 4 4 6/5 + 4 8/4 = (Must simplify and divide)

Ex. 5 5 1/4 – 1 3/4 = (Must regroup)

Ex. 6 1 2/15 + 7 1/6 = (Unlike denominators)

Independent Practice: 4 3/7 – 1 5/7 = 5 – 3/11 = 15 – 13 4/5= 7 3/4 – 5 2/3 =
