To simplify this expression, we need to find a common denominator for the fractions involved.
First, let's find the least common multiple (LCM) of 6, 15, and 12, which is 60.
Now, let's rewrite the expression with the common denominator of 60:
5/6 × 9/15 - 5/12 × 4/1= (5/6) × (9/15) - (5/12) × (4/15= (5/6) × (36/60) - (5/12) × (20/60= (30/60) - (25/60= 5/6= 1/12
Therefore, 5/6 × 9/15 - 5/12 × 4/15 = 1/12.

5/6 × 9/15 - 5/12 × 4/1
= (5/6) × (9/15) - (5/12) × (4/15
= (5/6) × (36/60) - (5/12) × (20/60
= (30/60) - (25/60
= 5/6
= 1/12
Therefore, 5/6 × 9/15 - 5/12 × 4/15 = 1/12.
