Answer 1

Answer:

don't know what is the meaning of estimate estimate

Answer 2

Tip:

• Estimate means to find a value that is close to the right answer.
• Rounding off means a number is made simple by keeping its value close to what it was.

Explanation:

• Given the numbers $11\div 4432, 13\div 6347, 17\div 4349,21\div 5136,47\div 6789$
• We have to estimate these numbers.
• We will find the answer by concept of estimation.

Steps:

Step 1 of 5:

Round off $11$ to the nearest ones is $10$

Round off $4432$ to the nearest hundred is $4000$

Estimate of $11\div 4432$ is $10\div 4000$ and the answer is $400$

Step 2 of 5:

Round off $13$ to the nearest ones is $10$

Round off $6347$ to the nearest hundred is $6000$

Estimate of $13\div 6347$ is $10\div 6000$ and the answer is $600$

Step 3 of 5:

Round off $17$ to the nearest ones is $20$

Round off $4349$ to the nearest hundred is $4000$

Estimate of $17\div 4349$ is $20\div 4000$ and the answer is $200$

Step 4 of 5:

Round off $21$ to the nearest ones is $20$

Round off $5136$ to the nearest hundred is $5000$

Estimate of $21\div 5136$ is $20\div 5000$ and the answer is $250$

Step 5 of 5:

Round off $47$ to the nearest ones is $50$

Round off $6789$ to the nearest hundred is $7000$

Estimate of $47\div 6789$ is $50\div 7000$ and the answer is $14$

Final Answer:

The answer of 1) is $400$

The answer of 2) is c) $600$

The answer of 3) is a) $200$

The answer of 4) is a) $250$

The answer of 5) is c) $14$
