Question

(1/4-5/6):2 1/3 +1/6*3/5=​

Answer 1

Ответ:

-0,15

Пошаговое объяснение:

1)1/4-5/6= -7/12

2)-7/3*3/7=-21/84=-1/4

3)1/6*3/5=3/30=1/10

4)-1/4+1/10=-5/20+2/20=-3/20=-0,15

Answer 2

Let's break down the expression step by step:

1. First, let's simplify the fractions in the expression: (1/4 - 5/6) / 2 + (1/6 * 3/5)

2. Find a common denominator for the fractions in the first part of the expression: To do this, we can find the least common multiple (LCM) of 4 and 6, which is 12.

3. Rewrite the fractions with the common denominator of 12: ((3/12) - (10/12)) / 2 + (1/6 * 3/5)

4. Simplify the first part of the expression within the parentheses: (-7/12) / 2 + (1/6 * 3/5)

5. Divide the fraction (-7/12) by 2: (-7/12) / 2 = -7/24

6. Continue with the second part of the expression: -7/24 + (1/6 * 3/5)

7. Multiply the fractions in the second part of the expression: (1/6 * 3/5) = (1/2 * 1/5) = 1/10

8. Now, add the two results together: -7/24 + 1/10

9. Find a common denominator for the fractions: To do this, we can find the LCM of 24 and 10, which is 120.

10. Rewrite the fractions with the common denominator of 120: (-35/120) + (12/120)

11. Add the fractions together: (-35/120) + (12/120) = (-35 + 12)/120 = -23/120

So, the final simplified result of the expression is -23/120.
