Answer 2

To simplify the expression (-1 3/25) × 2 1/7 + (-2 1/9) × (-27/190), we'll perform the calculations step by step.

Step 1: Convert the mixed numbers to improper fractions.

-1 3/25 = -28/25 2 1/7 = 15/7 -2 1/9 = -19/9

Step 2: Multiply the fractions.

(-28/25) × (15/7) + (-19/9) × (-27/190)

Step 3: Simplify each multiplication.

(-28/25) × (15/7) = (-4/5) × (3/1) = -12/5 (-19/9) × (-27/190) = (19/9) × (27/190) = 513/1710

Step 4: Add the two results.

-12/5 + 513/1710

Step 5: Find a common denominator for the fractions.

The common denominator for 5 and 1710 is 8550.

(-12/5) × (1710/1710) + (513/1710) × (5/5) = (-2040/8550) + (2565/8550)

Step 6: Add the fractions.

(-2040/8550) + (2565/8550) = 525/8550

Step 7: Simplify the fraction if possible.

525/8550 = 1/16
