Answer:
To evaluate the expression, 7/8*3/7+7/8*(-4/21) + (-5/24), we can follow the order of operations which is also known as PEMDAS.
PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. It tells us the order in which we need to perform the operations.Let's solve the given expression:7/8 * 3/7 = (7 * 3) / (8 * 7) = 21 / 56 = 3 / 8 7/8 * (-4/21) = (7 * -4) / (8 * 21) = -28 / 168 = -1 / 6Adding the above two results and subtracting (-5/24) from it, we get: (3/8) + (-1/6) - (5/24) = (9/24) - (4/24) - (5/24) = 0/24 = 0Therefore, the value of the expression 7/8*3/7+7/8*(-4/21) + (-5/24) is 0.
