Answer 2

To solve the expression (0.75 + 6/7 - 3/4) * 49/66, follow the order of operations (PEMDAS/BODMAS):

Step 1: Simplify the addition and subtraction inside the parentheses: 0.75 + 6/7 - 3/4 = 0.75 + (24/28) - (21/28) = 0.75 + (24 - 21)/28 = 0.75 + 3/28

Step 2: Find a common denominator for the addition: 0.75 + 3/28 = (21/28) + (3/28) = 24/28 = 6/7

Step 3: Multiply the result from Step 2 by 49/66: (6/7) * (49/66) = (6 * 49) / (7 * 66) = 294 / 462 = 7/11

Therefore, the result of the expression (0.75 + 6/7 - 3/4) * 49/66 is 7/11.
