Final answer:
To divide 18 by 54.36, you can use a calculator or do long division. The quotient, rounded to four significant figures, is approximately 0.3311. This division demonstrates the importance of decimal placement in calculations.
Step-by-step explanation:
To divide 18 by 54.36, you would typically use a calculator or perform long division. The process using a calculator is straightforward. However, with long division, you'd set it up with 18 as the dividend inside the division bar and 54.36 as the divisor outside. Since 54.36 is more than 18, we know the result will be less than one. You would then proceed to divide as you would with whole numbers, potentially having to add decimal places to the dividend (18.000) to complete the division.
When you perform this division, the quotient will be approximately 0.3311 when rounded to four significant figures.
Keeping track of the decimal point is crucial when dividing decimals. For example, if we divide 1.9436 by 100, the decimal moves two places to the left, giving us 0.019436. This is similar to understanding how to handle decimals when dividing, ensuring that your answer has the correct decimal placement.
