Exercise #1

Which figure shows a shape with34 \frac{3}{4} of its area shaded in red?

Video Solution

Step-by-Step Solution

To solve this problem, follow these steps:

  • Step 1: Examine each figure to determine the total number of equal parts.
  • Step 2: Identify how many parts are shaded in red for each figure.
  • Step 3: Calculate the fraction of the shaded area over the total area for each figure.
  • Step 4: Determine which figure has the fraction 34\frac{3}{4} shaded in red.

Now, let's work through these steps:

Step 1: Upon examining the figures provided:

  • Figure A is divided into 4 equal parts, with 1 part shaded.
  • Figure B is divided into 4 equal parts, with 2 parts shaded.
  • Figure C is divided into 4 equal parts, with 3 parts shaded.
  • Figure D is divided into 4 equal parts, with all 4 parts shaded.

Step 2: Calculate the shaded fraction for each figure:

  • Figure A: 14\frac{1}{4} shaded.
  • Figure B: 24=12\frac{2}{4} = \frac{1}{2} shaded.
  • Figure C: 34\frac{3}{4} shaded.
  • Figure D: 44=1\frac{4}{4} = 1 shaded.

Step 3: Identify which figure has 34\frac{3}{4} of its area shaded:

  • Only Figure C has 34\frac{3}{4} of its area shaded in red.

Therefore, the solution to the problem is that Figure C correctly shows 34\frac{3}{4} of its area shaded in red.

Answer

Exercise #2

Choose the shape in which the painted part is 25 \frac{2}{5}

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: For each shape, count the total number of equal segments.
  • Step 2: Count the number of segments that are painted.
  • Step 3: Calculate the fraction of the painted area by dividing the number of painted segments by the total number of segments.
  • Step 4: Identify the shape where the fraction of painted area is 25 \frac{2}{5} .

Now, let's work through each step:

Step 1: Let's examine the shapes given in the choices.

Step 2: For choice 3, the shape has 5 equal segments. Two of these segments are painted.

Step 3: Calculate the fraction for choice 3:

Number of painted partsTotal number of parts=25 \frac{\text{Number of painted parts}}{\text{Total number of parts}} = \frac{2}{5}

Step 4: Therefore, choice 3 is the correct shape with 25 \frac{2}{5} of the area painted.

Therefore, the solution to the problem is the shape from choice 3, where 25 \frac{2}{5} of the area is painted.

Exercise #3

Choose the shape in which the painted part is 27 \frac{2}{7}

Video Solution

Step-by-Step Solution

To solve this problem, we'll determine which shape has a fraction of 27 \frac{2}{7} of its sections painted:

  • Step 1: Analyze the given choices to determine the total number of sections in each shape.
  • Step 2: Count the number of painted sections in each shape.
  • Step 3: Calculate the fraction of painted sections for each shape.
  • Step 4: Identify which, if any, of the fractions is equal to 27 \frac{2}{7} .

Let's go through these steps with the shapes provided:

Choice 1: This shape is divided into 5 sections (3 empty, 2 painted):

The fraction of painted sections =25= \frac{2}{5}.

Choice 2: This shape is divided into 7 sections (5 empty, 2 painted):

The fraction of painted sections =27= \frac{2}{7}.

Choice 3: This shape is divided into 7 sections, same as choice 2:

The fraction of painted sections =27= \frac{2}{7}.

Choice 4: This shape is divided into 7 sections (5 empty, 2 painted):

The fraction of painted sections =27= \frac{2}{7}.

Both Choice 2 and Choice 4 have exactly the fraction 27 \frac{2}{7} of the sections painted. Since we are looking for one choice, we’ll choose the first (Choice 2) based on its placement in the sequence.

Therefore, the shape which represents a fraction of the painted part of 27 \frac{2}{7} is found in Choice 2.
