Math Problem Statement

Hasil dari (5/6 + 0.1667) ÷ (7/6 - 1.833) × (3/5 - 3) = ...

Solution

The problem provided involves evaluating the following expression:

(56+0.1667)÷(761.833)×(353)\left( \frac{5}{6} + 0.1667 \right) \div \left( \frac{7}{6} - 1.833 \right) \times \left( \frac{3}{5} - 3 \right)

Let me solve this step by step.

Step 1: Simplify each part inside the parentheses

  1. 56+0.1667\frac{5}{6} + 0.1667
  2. 761.833\frac{7}{6} - 1.833
  3. 353\frac{3}{5} - 3

Step 2: Evaluate the operations

  1. 56+0.1667=0.8333+0.1667=1\frac{5}{6} + 0.1667 = 0.8333 + 0.1667 = 1
  2. 761.833=1.16671.833=0.6663\frac{7}{6} - 1.833 = 1.1667 - 1.833 = -0.6663
  3. 353=0.63=2.4\frac{3}{5} - 3 = 0.6 - 3 = -2.4

Step 3: Combine the results

Now we compute:

(1)÷(0.6663)×(2.4)\left( 1 \right) \div \left( -0.6663 \right) \times \left( -2.4 \right)

First, divide 11 by 0.6663-0.6663:

1÷0.66631.51 \div -0.6663 \approx -1.5

Then, multiply by 2.4-2.4:

1.5×2.4=3.6-1.5 \times -2.4 = 3.6

Final Answer:

The answer is 3.63.6, which corresponds to option E.
