Answer 2

To simplify the expression 1 7/12 ÷ (3/8 + 5/12), we can follow these steps:

Step 1: Convert the mixed number 1 7/12 to an improper fraction. 1 7/12 = (12 × 1 + 7)/12 = 19/12

Step 2: Simplify the expression inside the parentheses. 3/8 + 5/12 = (3/8) × (3/3) + (5/12) × (2/2) = 9/24 + 10/24 = 19/24

Step 3: Divide the numerator (19) of the fraction 19/12 by the denominator (12) and multiply the result by the reciprocal of the simplified fraction (19/24). (19/12) ÷ (19/24) = (19/12) × (24/19) = (19 × 24) / (12 × 19) = 456/228 = 2

Therefore, 1 7/12 ÷ (3/8 + 5/12) simplifies to 2.
