The image contains a coloring page with mathematical problems and a legend associating fractions with colors. The task is to solve the math problems and assign colors based on the legend.

Coloring Instructions:

• Calculate the value of each fraction/equation.
• Match the result with the corresponding color from the legend.
• Color the parts of the castle according to the legend.

Legend and Calculations:

• 1/3 - фиолетовый (Purple): Result = 0.33...
• 4/7 - тёмно-зелёный (Dark Green): Result = 0.57...
• 2/3 - жёлтый (Yellow): Result = 0.66...
• 3/5 - оранжевый (Orange): Result = 0.6
• 7/9 - синий (Blue): Result = 0.77...
• 7/20 + 2/5 (7/20 + 8/20) = 15/20 = 3/4 = 0.75
• 1/14 + 3/7 (1/14 + 6/14) = 7/14 = 1/2 = 0.5
• 2/21 + 4/7 (2/21 + 12/21) = 14/21 = 2/3 (Yellow)
• 17/18 - 1/6 (17/18 - 3/18) = 14/18 = 7/9 (Blue)
• 3/5 (This is likely a segment of the castle, or a standalone problem. If it's a standalone problem, the color is Orange.)
• 8/45 + 3/5 (8/45 + 27/45) = 35/45 = 7/9 (Blue)
• 1 1/8 - 5/8 (9/8 - 5/8) = 4/8 = 1/2 = 0.5
• 5/28 + 4/7 (5/28 + 16/28) = 21/28 = 3/4 = 0.75
• 11/16 - 5/8 (11/16 - 10/16) = 1/16 = 0.0625
• 1 1/2 - 1/4 (3/2 - 1/4) = 6/4 - 1/4 = 5/4 = 1.25
• 1/2 + 1/4 = 2/4 + 1/4 = 3/4 = 0.75
• 6/28 + 3/14 (6/28 + 6/28) = 12/28 = 3/7 = 0.42...
• 3/16 + 1/4 (3/16 + 4/16) = 7/16 = 0.4375
• 5/33 + 2/3 (5/33 + 22/33) = 27/33 = 9/11 = 0.81...
• 10/21 + 2/5 (50/105 + 42/105) = 92/105 = 0.87...
• 7/12 - 1/4 (7/12 - 3/12) = 4/12 = 1/3 (Purple)
• 13/36 - 3/4 (13/36 - 27/36) = -14/36 = -7/18 = -0.38...
• 1/2 - 3/4 (2/4 - 3/4) = -1/4 = -0.25
• 42/12 + 1/6 (21/6 + 1/6) = 22/6 = 11/3 = 3.66...
• 3/4 - 3/5 (15/20 - 12/20) = 3/20 = 0.15
• 9/11 - розовый (Pink)
• 9/14 - тёмно-коричневый (Dark Brown)
• 7/16 - красный (Red)
• 5/18 - салатовый (Light Green)

Additional Colors:

• 3/4 (from 7/20 + 2/5, 5/28 + 4/7, 1/2 + 1/4) - The color for 3/4 is not explicitly listed in the legend. Based on common coloring activities, it might be intended to match one of the provided fractions or have a default color. Assuming it aligns with a fraction close to it or a common color for such results. If we must pick from the legend, we would look for values near 0.75.

Note: Some results might be negative or outside the range of provided fractions, indicating potential issues with the problem design or missing color associations for certain results.
