Question

(4 20/36-3 21/36):(-35/27) ​

Answer 1

(4 20/36 - 3 21/36) : (-35/27) = -3/4

1) 4 20/36 - 3 21/36 = 3 56/36 - 3 21/36 = 35/36

2) 35/36 : (-35/27) = 35/36 · (-27/35) = -27/36 = -3/4

Ответ: (-3/4) или (-0,75) в десятичных дробях.

Answer 2

To solve this expression, first simplify the fractions and then perform the operations.

1. Simplify the fractions:

   • 20/36 simplifies to 5/9 (both the numerator and denominator are divisible by 4).
   • 21/36 simplifies to 7/12 (both the numerator and denominator are divisible by 3).

2. Perform the subtraction: (5/9 - 7/12) = [(4 * 5)/(4 * 9) - (3 * 7)/(3 * 12)] = (20/36 - 21/36)

3. Now, subtract the fractions: (20/36 - 21/36) = (20 - 21)/36 = -1/36

4. Finally, divide the result by (-35/27): (-1/36) / (-35/27) = (-1/36) * (-27/35)

To simplify further, you can cancel common factors: (-1/36) * (-27/35) = (1/36) * (27/35)

Now, multiply the fractions: (1/36) * (27/35) = (1 * 27)/(36 * 35)

Further simplify: (27/1260)

The final result is 27/1260, which can be reduced to its simplest form if necessary.
