Final answer:
13.80 divided by 11.80 results in approximately 1.17 when rounded to two decimal places. Calculators perform exact operations but users must determine the significance of the decimal places in the result.
Step-by-step explanation:
The division of 13.80 by 11.80 can be carried out by a simple division operation. The provided list of figures seems to suggest similar calculations where division is performed, potentially with different dividends and divisors. When calculators are used, they execute the exact mathematical operations asked of them. However, as noted in the reference material, calculators present results without considering the significance of the figures involved in the operation, hence, the human operator should make decisions on reporting the significance of the results.
To divide 13.80 by 11.80 manually or using a basic calculator, you would perform the following steps:
Input the dividend, which is 13.80.
Input the division symbol (/).
Input the divisor, which is 11.80.
Execute the operation to get the result.
The exact result of this calculation is 1.1694915254237288. If rounding to two decimal places, as is often conventional, the result would be approximately 1.17.
