Question

(8 - 7 13/14) × (2 1/4 +3 1/3 - 4 11/15)×1​

Answer 1

(8 - 7 13/14) × (2 1/4 +3 1/3 - 4 11/15)×1​

1) 8 - 7 13/14 = 7 14/14 - 7 13/14 = 1/14

2) 2 1/4⁽³ + 3 1/3⁽⁴ = 2 3/12 + 3 4/12 = 5 7/12

3) 5 7/12⁽⁵ - 4 11/15⁽⁴ = 5 35/60 - 4 44/60 = 335/60 - 244/60 = 91/60 = 1 31/60

4) 1/14 * 1 31/60 = 91/840

Answer 2

To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) and simplify step by step.

Given expression:

(8 - 7 13/14) × (2 1/4 + 3 1/3 - 4 11/15) × 1

Let's start with the calculations:

1. Calculate the values inside the parentheses/brackets first:

   • For the first set of parentheses: 8 - 7 13/14 = 8 - (7 + 13/14) = 8 - (98/14 + 13/14) = 8 - 111/14 = 8 - 7 13/14

   • For the second set of parentheses: 2 1/4 + 3 1/3 - 4 11/15 = (8/4 + 1/4) + (10/3 + 1/3) - (60/15 + 11/15) = 2 + 1 + 3 - 4 = 2

2. Now, substitute the results back into the expression: (8 - 7 13/14) × (2 1/4 + 3 1/3 - 4 11/15) × 1 = (8 - 7 13/14) × 2 × 1 = (8 - 7 13/14) × 2

3. Substituting the value of (8 - 7 13/14): (8 - 7 13/14) × 2 = (8 - 7) × 2 = 1 × 2 = 2

So, the final result of the given expression is 2.
