Questions & Answers

Q: How do you convert a number from base 7 to base 5?

To convert a number from base 7 to base 5, first convert it to base 10 by multiplying each digit with the corresponding power of 7. Then, convert the obtained base 10 number to base 5 by repeatedly dividing and noting the remainders.

Q: What is the process of converting from base 10 to base 5?

Converting from base 10 to base 5 involves repeatedly dividing the number by 5 and noting the remainders. The remainders are then written down in reverse order to obtain the number in base 5.

Q: What is the significance of the repeated divisions in converting to base 5?

The repeated divisions in converting to base 5 help determine the remainders at each step, which are necessary to represent the number in base 5. By dividing the number by 5 multiple times, we can identify the remainders and write them in reverse order to obtain the base 5 form.

Q: How can you check the accuracy of the conversion process?

To check the accuracy of the conversion process, you can convert the resulting number from base 5 back to base 7 and verify if it matches the original number. By following the reverse process of conversion, you can ensure the correctness of your calculations.

Summary & Key Takeaways

• Convert the given number from base 7 to base 10 by multiplying each digit with the corresponding power of 7 and adding them up.

• After obtaining the base 10 form, convert it to base 5 by repeatedly dividing and noting the remainders.

• Write down the remainders in reverse order to obtain the number in base 5.
