Answer 2

(5/ 6* 5- 5): 2/ 3- 0,25 = (25/6 - 5) * 2/3 - 1/4 = - 5/6 * 2/3 - 1/4 = - 5/6 * 2/3 - 1/4 = - 5/3 * 1/3 - 1/4 = - 5/9 - 1/4 = - 29/36

Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

P - Parentheses/Brackets E - Exponents/Orders (none in this case) MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

Now let's solve the expression step-by-step:

(5/6 * 5 - 5) = (5/6 * 5) - 5 = (5/6 * 5) - 5/1 [5 can be expressed as 5/1]

Next, perform the multiplication:

(5/6 * 5) = (5 * 5)/(6 * 1) [Multiplying fractions: (a/b) * (c/d) = (a * c)/(b * d)] = 25/6

Now, substitute this back into the original expression:

(25/6) - 5/1

Next, find a common denominator, which is 6:

(25/6) - (30/6)

Now subtract:

25/6 - 30/6 = (25 - 30)/6 = -5/6

Finally, we have the expression:

(-5/6) - 0.25

To subtract fractions, we need a common denominator, which is 6:

(-5/6) - (0.25 * 6/6)

(-5/6) - (1.5/6)

Now subtract:

(-5 - 1.5)/6 = -6.5/6

Since -6.5/6 is an improper fraction, we can simplify it to a mixed number:

-6.5 ÷ 6 = -1 with a remainder of -0.5

So the final answer is approximately:

-1 - 0.5 = -1.5
