Answer 3

To solve the given expression, let's break it down step by step:

Step 1: Calculate (10/21) × (-14/25) (10/21) × (-14/25) = -140/525 = -4/15

Step 2: Calculate (-4/15) × (8/5) (-4/15) × (8/5) = -32/75

Step 3: Calculate (-24/35) × (15/28) × (49/60) (-24/35) × (15/28) × (49/60) = -1680/5880 = -4/14 = -2/7

Step 4: Calculate (-25/32) × (-8/55) × (-44/75) (-25/32) × (-8/55) × (-44/75) = 4400/52800 = 11/132

Step 5: Add the results from step 2 and step 4: -32/75 + 11/132 = (-32 * 132 + 11 * 75) / (75 * 132) = (-4224 + 825) / 9900 = -3399 / 9900

Therefore, the final result of the given expression is -3399/9900.
