Answer 1

Ответ:

(6 2/9-5 5/6):(7/36) =( 6 8/36-5 25/36)*36/7=19/36*36/7=2 5/7

1,3-3,6(X-3)=5*(8-0,4Х)

1,3-3,6х-10,8=40-2х

-3,6х+2х=40-1,3+10,8

-1,6х=49,5

х=-49,5:1,6

х=-3 15/16

Answer 2

To solve the expression (6 2/9 - 5 5/6) : (-7/16), we'll follow the order of operations (PEMDAS/BODMAS).

Step 1: Convert mixed numbers to improper fractions: 6 2/9 can be written as (6 * 9 + 2) / 9 = 56/9 5 5/6 can be written as (5 * 6 + 5) / 6 = 35/6

Step 2: Rewrite the expression using the division symbol (÷): (56/9 - 35/6) ÷ (-7/16)

Step 3: Simplify the subtraction: To subtract fractions, we need to find a common denominator. The common denominator for 9 and 6 is 18.

(56/9 - 35/6) ÷ (-7/16) = (56/9 * 2/2 - 35/6 * 3/3) ÷ (-7/16) = (112/18 - 105/18) ÷ (-7/16) = 7/18 ÷ (-7/16)

Step 4: Invert the divisor and multiply: To divide by a fraction, we multiply by its reciprocal.

7/18 ÷ (-7/16) = 7/18 * (-16/7) = -16/18 = -8/9

Therefore, the value of (6 2/9 - 5 5/6) : (-7/16) is -8/9.
