Examples with solutions for Part of an Amount: Identify the greater value

Exercise #1

Choose the way in which the painted part is greater than 35 \frac{3}{5}

Video Solution

Step-by-Step Solution

To solve this problem, we'll analyze each representation:

  • Step 1: Identify the divisions and colored sections in each representation.
  • Step 2: Convert the colored sections to fractions relative to the total divisions.
  • Step 3: Compare each fraction with 35 \frac{3}{5} .

Let's apply these steps:

Choice 1: The rectangle is divided into 5 parts with 3 parts colored on the left and 1 part colored on the right, so this represents 35+15=45 \frac{3}{5} + \frac{1}{5} = \frac{4}{5} . This is greater than 35 \frac{3}{5} .

Choice 2: The rectangle shows 1 part colored out of 5 total, 15 \frac{1}{5} , which is less than 35 \frac{3}{5} .

Choice 3: Similar to Choice 2, it shows 1 part colored out of 5 total, 15 \frac{1}{5} , which is also less than 35 \frac{3}{5} .

Choice 4: Two sections each representing 15 \frac{1}{5} , totaling 25 \frac{2}{5} , which is less than 35 \frac{3}{5} .

Therefore, the correct choice is Choice 1 where the painted part, 45 \frac{4}{5} , is greater than 35 \frac{3}{5} .

Answer

Exercise #2

In which example below does the colored section account for more than a 15 \frac{1}{5} of the shape as a whole?

Video Solution

Step-by-Step Solution

To find the shape where the colored section accounts for more than 15 \frac{1}{5} of the whole, we'll follow these steps:

  • Step 1: Count the total number of sections in each shape.
  • Step 2: Count the number of sections that are colored.
  • Step 3: Calculate the fraction represented by the colored sections.
  • Step 4: Compare this fraction with 15 \frac{1}{5} .

Let's apply this to the given choices:

**Choice 1:**
The shape is comprised of 6 sections, with 2 sections being colored.
The fraction of the shape that is colored is 26=13 \frac{2}{6} = \frac{1}{3} .
Since 13 \frac{1}{3} is greater than 15 \frac{1}{5} , this choice meets the condition.

**Choice 2:**
The shape is similar but has only 1 section colored out of 6 in total.
The fraction is 16 \frac{1}{6} , which is less than 15 \frac{1}{5} . This does not satisfy the condition.

**Choice 3:**
Here, 1 out of 5 sections is colored.
The fraction is 15 \frac{1}{5} , which is exactly 15 \frac{1}{5} but not more than 15 \frac{1}{5} .

**Choice 4:**
This shape has 1 out of 6 sections colored.
The fraction is 16 \frac{1}{6} , which is less than 15 \frac{1}{5} .

Therefore, in the example corresponding to Choice 1, the colored sections indeed account for more than 15 \frac{1}{5} of the entire shape.

The correct answer is Choice 1.

Answer

Exercise #3

Choose the way in which the painted part is greater than 19 \frac{1}{9}

Video Solution

Step-by-Step Solution

Let's solve the problem by following these steps:

  • Step 1: Identify the total and painted sections in each illustration.
  • Step 2: Calculate the fraction of painted sections.
  • Step 3: Compare each fraction to 19\frac{1}{9}.

Now, let's analyze each choice:

Choice 1: The illustration shows one painted section out of 9 total sections, so the fraction is 19\frac{1}{9}.

Choice 2: The illustration shows three painted sections out of 9 total sections, so the fraction is 39=13\frac{3}{9} = \frac{1}{3}.

Choice 3: The illustration shows one painted section out of 9 total sections, which equals 19\frac{1}{9}.

Choice 2's 13\frac{1}{3} is greater than 19\frac{1}{9} since 13=39\frac{1}{3} = \frac{3}{9}.

Thus, the configuration in Choice 2 represents a painted part that is greater than 19\frac{1}{9}.

Therefore, the option with a painted part greater than 19\frac{1}{9} is Choice 2.

Answer

Exercise #4

Choose the way in which the painted part is greater than 25 \frac{2}{5}

Video Solution

Step-by-Step Solution

To solve the problem, we need to determine which option displays parts painted more than 25\frac{2}{5}.

  • Step 1: Each option shows an arrangement divided into 5 boxes. We seek parts painted red exceeding 25\frac{2}{5}.

  • Step 2: Analyze each visual:
    -- Option 1, 1 block painted out of 5, fraction = 15\frac{1}{5}.
    -- Option 2, 2 out of 5 blocks painted, fraction = 25\frac{2}{5}.
    -- Option 3, 3 blocks painted out of 5, fraction = 35\frac{3}{5}.
    -- Option 4, 1 block painted out of 5, fraction = 15\frac{1}{5}.

  • Step 3: Compare 35\frac{3}{5} in Option 3 with 25\frac{2}{5}.

Therefore, the only choice where the painted part is greater than 25\frac{2}{5} is Option 3.

Answer

Exercise #5

Choose the way in which the painted part is greater than 13 \frac{1}{3}

Video Solution

Step-by-Step Solution

To solve this problem, we'll visually evaluate the proportion of the painted area relative to the entire space for each choice and compare it with 13 \frac{1}{3} .

  • First, observe each provided choice, ensuring painted portions are clearly defined.
  • Count how many sections each graphic is divided into. The total sections represent the whole area.
  • Determine the number of sections painted in red. This represents the painted area.
  • Calculate the fraction of the painted area by dividing the number of painted sections by the total number of sections.
  • Compare these fractions with 13 \frac{1}{3} :
    • Choice 1: 1 section painted out of 3 total sections, 13 \frac{1}{3}
    • Choice 2: 1 section painted out of 3 total sections, 13 \frac{1}{3}
    • Choice 3: 2 sections painted out of 3 total sections, 23 \frac{2}{3}
  • According to the calculations, Choice 3 results in a painted fraction of 23 \frac{2}{3} , which is greater than 13 \frac{1}{3} . Therefore, Choice 3 has the painted part greater than 13 \frac{1}{3} .

Hence, the way in which the painted part is greater than 13 \frac{1}{3} is represented by Choice 3.
