-10/11 divided by -2/5
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
So, (-10/11) ÷ (-2/5) = (-10/11) * (-5/2)
This simplifies to (10/11) * (5/2) = (50/22)
The fraction can be simplified further by dividing both the numerator and denominator by their greatest common factor, which is 2.
So, (50/22) = (25/11)
Therefore, -10/11 divided by -2/5 is equal to 25/11.
As a mixed number?
To convert the fraction 25/11 into a mixed number, we divide the numerator (25) by the denominator (11).
25 ÷ 11 = 2 with a remainder of 3.
So, the mixed number is 2 and 3/11.
-3/4 divided by 3/8?
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
So, (-3/4) ÷ (3/8) = (-3/4) * (8/3)
Next, we'll simplify the fraction by reducing the numerator and denominator:
(-3/4) * (8/3) = (-3 * 8) / (4 * 3) = -24/12
The fraction -24/12 can be simplified by dividing both the numerator and denominator by their greatest common factor, which is 12.
-24/12 = -2/1 = -2
Therefore, -3/4 divided by 3/8 is equal to -2.
-2 3/5 divided by 4/5
To divide a mixed number by a fraction, we first convert the mixed number into an improper fraction.
-2 3/5 can be written as -13/5 as an improper fraction.
So, (-13/5) ÷ (4/5) = (-13/5) * (5/4)
Once we cancel out the common factors, the expression simplifies to:
(-13 * 5) / (5 * 4) = -65/20
The fraction -65/20 can be further simplified by dividing both the numerator and denominator by their greatest common factor, which is 5.
-65/20 = -13/4
Therefore, -2 3/5 divided by 4/5 is equal to -13/4.
What one way to compare animal and plant cells?
One way to compare animal and plant cells is by looking at their structures and organelles. Although both types of cells have many similarities, there are some key differences.
1. Cell Wall: Plant cells have a rigid cell wall made of cellulose that provides support and shape to the cell. Animal cells do not have a cell wall.
2. Chloroplasts: Plant cells contain chloroplasts, which are organelles responsible for photosynthesis. Chloroplasts contain chlorophyll, a green pigment that captures sunlight for energy production. Animal cells do not have chloroplasts.
3. Vacuoles: Plant cells typically have a large central vacuole that stores water, nutrients, and waste products. Animal cells may have smaller vacuoles, but they are not as prominent as in plant cells.
4. Shape: Animal cells are generally round or irregular in shape, while plant cells are more rectangular or square due to the rigid cell wall.
These are just a few examples of the differences between animal and plant cells. It is important to note that despite these variations, both types of cells share many common organelles and functions such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.
What is confusing and challenging about understanding the functions of organelles?
Understanding the functions of organelles in cells can be confusing and challenging for several reasons:
1. Complexity: Cells are incredibly complex structures, and organelles play specific roles within these systems. Trying to grasp the intricate functions and interactions of multiple organelles can be overwhelming.
2. Overlapping Functions: Some organelles have overlapping functions, and it can be difficult to distinguish between their roles. For example, both the endoplasmic reticulum and Golgi apparatus are involved in protein synthesis and modification, making it challenging to understand the exact contributions of each organelle.
3. Interconnectedness: Organelles do not work in isolation but rather function in coordination with each other. This interdependence can make it challenging to isolate the specific role of one organelle without considering its interactions with others.
4. Specialized Functions: Many organelles have highly specialized functions that require a deep understanding of specific cellular processes and biochemical pathways. This specialized knowledge can make it difficult for individuals without a strong background in biology or biochemistry to fully grasp their functions.
5. Evolving Understanding: As scientific knowledge advances, our understanding of organelle functions continues to evolve. New research and discoveries sometimes challenge or alter previously accepted functions, adding to the complexity and confusion.
To overcome these challenges, it is helpful to approach the topic systematically, break down complex processes into simpler steps, utilize visual aids and illustrations, and seek out reliable resources or educational materials to enhance comprehension.
