Question

6(1/4к-5/6)-15(0,6-2 1/3

Answer 1

Ответ:

6к/4 - 5 -15*6/10+15*7*к/3=1.5к+15к-5-9= 36,5к-14

Answer 2

To simplify the expression 6(1/4k - 5/6) - 15(0.6 - 2 1/3), follow these steps:

Step 1: Simplify the fractions within the parentheses.

1/4k - 5/6 can be written as (3/12k - 10/12). This is done by finding a common denominator, which is 12 in this case.

Step 2: Distribute the constants outside the parentheses.

6 * (3/12k - 10/12) - 15 * (0.6 - 2 1/3)

Step 3: Simplify the expressions within the parentheses.

6 * (3/12k - 10/12) = (18/12k - 60/12)

15 * (0.6 - 2 1/3) = 15 * (0.6 - 7/3)

Step 4: Perform the subtraction within the parentheses.

15 * (0.6 - 7/3) = 15 * (-6/3 + 7/3) = 15 * (1/3)

Now, let's simplify the remaining expressions:

(18/12k - 60/12) - 15 * (1/3)

Step 5: Find a common denominator and subtract the fractions.

(18/12k - 60/12) - (15/3) = (18/12k - 60/12) - (5/1)

Step 6: Continue simplifying.

(18/12k - 60/12) - (5/1) = (18/12k - 60/12) - (60/12)

Step 7: Combine like terms.

(18/12k - 60/12) - (60/12) = (18/12k - 120/12)

Step 8: Simplify further by factoring out a common factor of 6 in the numerator.

(6/4k - 10)

Now, the expression is simplified to (6/4k - 10). You can leave it like this, or if you want, you can simplify it further by dividing both terms by 2:

(3/2k - 10)
