Understanding Fractions
A fraction shows parts of a whole Numerator = number of parts we have Denominator = total number of equal parts Same denominator = same-sized pieces

Keep the denominator the same Add only the numerators Example: 3/7 + 2/7 = 5/7 The whole stays divided into 7 equal parts
Subtracting Fractions - Same Denominator
Keep the denominator the same Subtract only the numerators Example: 5/7 - 2/7 = 3/7 We're taking away parts, not changing the size of pieces
