Answer:

113/24

Step-by-step explanation:

Simplify the following:

(14 + 1/8)/3

Put 14 + 1/8 over the common denominator 8. 14 + 1/8 = (8×14)/8 + 1/8:

((8×14)/8 + 1/8)/3

8×14 = 112:

(112/8 + 1/8)/3

112/8 + 1/8 = (112 + 1)/8:

((112 + 1)/8)/3

112 + 1 = 113:

(113/8)/3

113/8×1/3 = 113/(8×3):

113/(8×3)

8×3 = 24:

Answer: 113/24
