Answer 2

Let's break down these calculations step by step:

1. (-25 08) * 4 4/19 * (35/66) * (-3 1/7)

First, let's convert the mixed numbers into improper fractions for easier multiplication:

-25 08 = -25 + 8/100 = -25 + 1/12 = -25 1/12 -3 1/7 = -3 + 1/7

Now, the calculation becomes:

(-25 1/12) * (4 4/19) * (35/66) * (-3 + 1/7)

Next, multiply the fractions and whole numbers separately:

-25 1/12 * 4 4/19 * 35/66 * (-3 + 1/7) =

(-301/12) * (77/19) * (35/66) * (-20/7) =

Now, multiply the fractions:

(-301/12) * (77/19) * (35/66) * (-20/7) = (-301 * 77 * 35 * -20) / (12 * 19 * 66 * 7)

Now, calculate the numerator and denominator separately:

Numerator: (-301 * 77 * 35 * -20) = 39455500 Denominator: (12 * 19 * 66 * 7) = 109944

So, the result is:

39455500 / 109944

Now, you can simplify this fraction by finding the greatest common divisor (GCD) of the numerator and denominator, and then dividing both by the GCD.

GCD(39455500, 109944) = 12

Divide both the numerator and denominator by 12:

(39455500 / 12) / (109944 / 12) = 3287958.33333 / 9162 = 358.80082 (rounded to 5 decimal places)

So, the result is approximately 358.80082.

2. 27/68 * (-77,35) * (-5 20/21) * 4 12/13

First, convert mixed numbers into improper fractions:

-5 20/21 = -5 + 20/21

Now, the calculation becomes:

(27/68) * (-77.35) * (-5 + 20/21) * (4 12/13)

Next, multiply the fractions and whole numbers separately:

(27/68) * (-77.35) * (-5 + 20/21) * (4 12/13) =

(27/68) * (-77.35) * (-125/21) * (4 + 12/13)

Now, multiply the fractions:

(27/68) * (-77.35) * (-125/21) * (4 + 12/13) =

Now, calculate the numerator and denominator separately:

Numerator: (27 * -77.35 * -125 * 55) = 131933625 Denominator: (68 * 21 * 13) = 193548

So, the result is:

131933625 / 193548

Now, you can simplify this fraction by finding the greatest common divisor (GCD) of the numerator and denominator, and then dividing both by the GCD.

GCD(131933625, 193548) = 9

Divide both the numerator and denominator by 9:

(131933625 / 9) / (193548 / 9) = 14659291.66667 / 21494.22222 = 682.30062 (rounded to 5 decimal places)

So, the result is approximately 682.30062.
