Question

Изобразите в тетради такой же квадрат как на рисунке 79. Закрасьте 1\2 квадрата синим цветом 1\4 красным 1\8 жёлтым 1\16 зелёным. Какая часть квадрата осталась незакрашенной? Какая часть квадрата закрашена

Answer 1

1 - 1/2 - 1/4 - 1/8 = 1/8 - не закрашена.

Answer 2

Drawing the Square

To draw a square similar to the one shown in Figure 79, you can follow these steps:

1. Start with a blank page in your notebook. 2. Draw four straight lines of equal length to form a square shape. 3. Divide the square into smaller equal parts. Since the question mentions dividing the square into halves, quarters, eighths, and sixteenths, you will need to divide each side of the square accordingly. 4. Label the divisions on each side of the square to keep track of the different parts.

Coloring the Square

To color the square according to the given instructions, follow these steps:

1. Start with a blank square. 2. Color half of the square blue. This means that one of the two equal halves of the square should be colored blue. 3. Color one-fourth of the square red. This means that one of the four equal parts of the square should be colored red. 4. Color one-eighth of the square yellow. This means that one of the eight equal parts of the square should be colored yellow. 5. Color one-sixteenth of the square green. This means that one of the sixteen equal parts of the square should be colored green.

Remaining Unfilled Area

To determine the remaining unfilled area of the square, we need to calculate the sum of the colored parts and subtract it from the total area of the square.

The colored parts include: - Half of the square (blue) - One-fourth of the square (red) - One-eighth of the square (yellow) - One-sixteenth of the square (green)

To calculate the total area of the colored parts, we can add the fractions together:

1/2 + 1/4 + 1/8 + 1/16 = 15/16

Therefore, the colored parts of the square cover 15/16 of the total area.

To find the remaining unfilled area, we subtract the colored area from the total area of the square:

1 - 15/16 = 1/16

The remaining unfilled area of the square is 1/16.

Summary

In summary, to recreate the square shown in Figure 79 in your notebook, follow the steps outlined above. After coloring half of the square blue, one-fourth red, one-eighth yellow, and one-sixteenth green, you will have 15/16 of the square filled. The remaining unfilled area is 1/16 of the total square.
