Adding Fractions

Adding fractions requires a common denominator

A + C = AD + CB = AD + CB B + D = BD + BD = BD

Page 23: Fractions 1

Subtracting fractions requires a common denominator

A - C = AD - CB = AD - CB B - D = BD - BD = BD

Page 24: Fractions 1

Multiplying Fractions

Multiplying fractions is easy

A * C = AC B * D = BD

Page 25: Fractions 1

Dividing Fractions

Dividing fractions requires one more step

A / C = A*D = AD B D = B*C BC
