Add the numerators because the denominators are the same:
¼ + ¾= ¼ + 3 = ⁴⁄₄ = 1.
Subtract the numerators because the denominators are the same:
⅞-⅜=⅞-3=⁴⁄₈=½.
⅔×¾=2×3/3×4=⁶⁄₁₂=½.
Divide fractions by multiplying the first fraction by the reciprocal of the second:
⅚÷⅔= ⅚׳⁄₂= 5×3/6×2= ¹⁵⁄₁₂ = ⁵⁄₄
Find a common denominator (6):
½=³⁄₆, ⅓=²⁄₆.
Add: ³⁄₆+²⁄₆=⅚.
