Answer:

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

2/3 x 2/4 x 3/5 - 0.67 - 3.4 - 5.6

1) Simplify the multiplication of the fractions:

(2/3) x (2/4) x (3/5) = (2 x 2 x 3) / (3 x 4 x 5) = 12/60 = 1/5

2) Subtract the numbers:

1/5 - 0.67 - 3.4 - 5.6

3) Convert the fractions to decimals:

1/5 = 0.2

4) Subtract the decimals:

0.2 - 0.67 - 3.4 - 5.6 = -9.47

Therefore, the value of the given expression is -9.47.

answer:

To simplify the expression 2/3 x 2/4 x 3/5 - 0.67 - 3.4 - 5.6, let's break it down into smaller steps:

Step 1: Simplify the multiplication of the fractions.

- Multiply the numerators: 2 x 2 x 3 = 12.

- Multiply the denominators: 3 x 4 x 5 = 60.

- The result of the multiplication is 12/60, which can be simplified further.

Step 2: Simplify the fraction 12/60.

- Divide both the numerator and the denominator by their greatest common divisor, which is 12.

- 12 divided by 12 is 1, and 60 divided by 12 is 5.

- Therefore, 12/60 simplifies to 1/5.

Step 3: Subtract the decimals.

- Subtracting the decimals, we get:

- 0.67 - 3.4 - 5.6 = -9.67.

Step 4: Combine the fraction and the decimal.

- To combine the fraction 1/5 with the decimal -9.67, we need to find a common denominator.

- The common denominator is 5, so we need to multiply -9.67 by 5/5 to get a fraction with a denominator of 5.

- Multiplying -9.67 by 5/5, we get -48.35/5.

Step 5: Add the fraction and the decimal.

- Adding the fraction 1/5 to the decimal -48.35/5, we get:

- 1/5 + (-48.35/5) = -47.35/5.

Therefore, the simplified expression is -47.35/5.
