Final answer:
Given the unclear question '161 4', if it pertains to finding the remainder of 161 divided by 4, the remainder is 1. For calculations with significant figures, results are rounded to match the least precise measurement used in the calculation.
Step-by-step explanation:
The question '161 4' seems to have a typo preventing a clear understanding of what calculation needs to be performed. Assuming you are asking for the remainder when 161 is divided by 4, here is how you would find it:
- Divide 161 by 4.
- The division gives a quotient of 40 with a remainder.
- To find the remainder, multiply the quotient by the divisor and subtract from the original number: 161 - (4 x 40) = 161 - 160 = 1.
Therefore, the remainder is 1.
If the calculation involves significant figures, remember to round your final answer to match the least precise measurement in your calculation. When presented with an answer from a calculator, such as 921.996, and one of the numbers used in the calculation is 13.77, you would round the final answer to the hundredths place, resulting in 922.00, as the digit to be dropped is greater than 5.
