Question

(- 3/7 - 5/14 - 8/21)*3/14 + 1/8(С решением, палочки это как дробь)

Answer 1

1). -3/7-5/14=-2*3-5/14=-11/14
2). - 11/14-8/21=-3*11-2*8/42=-49/42=-1 1/6
3). -1 1/6*3/14=-7/6*3/14=-7*3/6*14=-21/84=-1/4
4). - 1/4+1/8=-2*1+1/8=-1/8

Answer 2

Вот решение. Не за что

Answer 3

Sure, I'll solve the expression step by step. To avoid any ambiguity, I'll represent fractions using the fraction bar ("/") instead of palochki.

Given expression: (-3/7 - 5/14 - 8/21) * 3/14 + 1/8

Step 1: Find a common denominator for the fractions in the parentheses. The common denominator for 7, 14, and 21 is 42.

Step 2: Convert all fractions in the parentheses to have a common denominator of 42. (-3/7) = (-3/7) * (6/6) = (-18/42) (-5/14) = (-5/14) * (3/3) = (-15/42) (-8/21) = (-8/21) * (2/2) = (-16/42)

So, the expression becomes: (-18/42 - 15/42 - 16/42) * 3/14 + 1/8

Step 3: Combine the fractions in the parentheses. = (-49/42) * 3/14 + 1/8

Step 4: Simplify the multiplication on the left side. = (-7/6) * 3/14 + 1/8

Step 5: Find a common denominator for (-7/6) and 14 on the left side. The common denominator for 6 and 14 is 42.

Step 6: Convert the fraction (-7/6) to have a common denominator of 42. (-7/6) = (-7/6) * (7/7) = (-49/42)

So, the expression becomes: (-49/42) * 3/14 + 1/8

Step 7: Now, multiply the fractions on the left side. = (-49/42) * (3/14) + 1/8

Step 8: Distribute the multiplication on the left side. = (-147/588) + 1/8

Step 9: Find a common denominator for (-147/588) and 8 on the left side. The common denominator for 588 and 8 is 588.

Step 10: Convert the fraction (-147/588) to have a common denominator of 588. (-147/588) = (-147/588) * (1/1) = (-147/588)

So, the expression becomes: (-147/588) + (1/8)

Step 11: Add the fractions on the left side. = (-147/588) + (74/588)

Step 12: Combine the fractions on the left side. = (-147 + 74)/588

Step 13: Simplify the fraction on the left side. = -73/588

So, the final simplified expression is: -73/588.
