CBSE Class 5 Mathematics Chapter 1 The Fish Tale NCERT Solutions

Yes, there is a poem about fish provided in the source material. It is titled "Fish vs. Humans" and is attributed to Rebecca Bell. The poem draws parallels between the lives of fish and humans, touching upon themes of freedom, confinement, and social groups.

When thinking about fishes, several shapes come to mind, such as ovals, triangles (for fins and tails), and elongated, streamlined bodies which can be approximated by rectangles or curves. To draw a fish using a square and a triangle, you can:

1. Start with a square or a rectangle for the main body of the fish.
2. Use a triangle for the tail fin, attaching it to one end of the body.
3. You can use smaller triangles or other shapes for dorsal and pectoral fins.
4. Add an eye (a circle) and a mouth.

This combination of shapes helps create a basic representation of a fish.

'Meen' is a word that means 'fish'. The name 'Meenakshi' is derived from this, meaning 'fish-eyed', referring to eyes that are large and beautiful like those of a fish. While the source doesn't name a specific person, many people can have eyes that are described as large or almond-shaped, which might be likened to fish eyes. Drawing such a face would involve depicting eyes that are proportionally larger and perhaps more rounded or elongated than typical, conveying a sense of beauty or expressiveness.

The source mentions that a White shark can be as long as 18 metres. Therefore, the biggest fish one can imagine, based on this information, is about 18 metres long.

The source indicates that the longest fish (like the White shark) is about 18 metres long, and it also mentions that the smallest fish is about 1 centimetre long. To find out how many times longer the big fish is than the small fish, we need to convert their lengths to the same unit.

We know that 1 metre = 100 centimetres.

So, the length of the longest fish in centimeters is:

$$18\; \backslash text\{\; metres\}\; \backslash times\; 100\; \backslash frac\{\backslash text\{centimetres\}\}\{\backslash text\{metre\}\}\; =\; 1800\; \backslash text\{\; centimetres\}$$

Now, we can find how many times longer the 1800 cm fish is compared to the 1 cm fish:

$$\backslash frac\{1800\; \backslash text\{\; cm\}\}\{1\; \backslash text\{\; cm\}\}\; =\; 1800\; \backslash text\{\; times\}$$

Therefore, the longest fish is 1800 times longer than the smallest fish.

First, let's estimate the weight of one child. Based on the provided answer, let's assume a child weighs about 35 kg.

To find the total weight of 12 children, we multiply the weight of one child by 12:

$$\backslash text\{Weight\; of\; 12\; children\}\; =\; 12\; \backslash times\; 35\; \backslash text\{\; kg\}$$

$$12\; \backslash times\; 35\; =\; 420\; \backslash text\{\; kg\}$$

So, 12 children like you put together will weigh about 420 kg.

From the previous question, we know that the weight of 12 children put together is 420 kg.

The source states that the weight of a Whale shark is 16,000 kg.

To find out how much more the whale shark weighs, we subtract the total weight of the 12 children from the weight of the whale shark:

$$\backslash text\{Difference\; in\; weight\}\; =\; \backslash text\{Weight\; of\; Whale\; shark\}\; -\; \backslash text\{Weight\; of\; 12\; children\}$$

$$\backslash text\{Difference\; in\; weight\}\; =\; 16,000\; \backslash text\{\; kg\}\; -\; 420\; \backslash text\{\; kg\}$$

$$16,000\; -\; 420\; =\; 15,580\; \backslash text\{\; kg\}$$

So, the Whale shark will weigh 15,580 kg more than 12 children like you put together.

This question is based on personal experience and observation. Many students may have seen the sea either in real life during a visit to the coast or through movies and pictures. The depth of the sea is a vast topic; while the source suggests it could be at least a thousand feet deep, the actual average depth of the ocean is much greater, around 12,100 feet (approximately 3,688 meters or over 12,000 feet).

This question asks about personal abilities and feelings. Knowing how to swim can make one feel more confident near water. High sea waves can be intimidating even for experienced swimmers due to their power and unpredictability. It is natural to feel a sense of awe or even fear when witnessing large waves.

Imagining the sea with high waves is a visual exercise. The height of sea waves can vary greatly depending on factors like wind speed, storm intensity, and the size of the water body. While the source suggests waves can go as high as 50 metres, in extreme conditions like tsunamis or hurricanes, waves can reach much greater heights. For a typical scenario, imagining waves of several meters is reasonable.

The problem states that a log boat travels at a speed of 4 km in one hour.

We need to find out how long it will take to travel a distance of 10 km.

Speed = Distance / Time

So, Time = Distance / Speed

Time = $10\; \backslash text\{\; km\}\; /\; 4\; \backslash text\{\; km/hour\}$

Time = $2.5\; \backslash text\{\; hours\}$

Alternatively, we can break it down:

In 1 hour, the boat travels 4 km.

In 2 hours, the boat travels $2\; \backslash times\; 4\; =\; 8\; \backslash text\{\; km\}$.

The remaining distance is $10\; \backslash text\{\; km\}\; -\; 8\; \backslash text\{\; km\}\; =\; 2\; \backslash text\{\; km\}$.

Since the boat travels 4 km in 1 hour, it travels 2 km in half an hour ($4\; \backslash text\{\; km\}\; /\; 2\; =\; 2\; \backslash text\{\; km\}$).

So, the total time taken is 2 hours + 1/2 hour = 2 and a half hours.

Therefore, it will take 2 and a half hours for the log boat to go a distance of 10 km.

This is a question that requires personal estimation. A person walking fast can typically cover a distance of about 4 to 5 kilometers in one hour. This speed can vary based on fitness level, terrain, and other factors.

The sun rises in the East. From your location, looking towards the East in the morning, you would typically see the rising sun itself. The sky in the East often appears in beautiful shades of orange, red, and yellow as the sun ascends. Depending on your surroundings, you might also see buildings, trees, or hills silhouetted against the dawn sky in the East.
