Question

Using abbreviations and the rules of the metric system, express the following quantities correctly. One hundred milliliters ______

Short answer

100 ml

Step-by-step solution

Identify the Metric Unit

The quantity given is 'one hundred milliliters.' The metric unit in use is 'milliliters,' which is commonly abbreviated as 'ml.'

Understand the Value and Prefix

The value provided is one hundred, which in numeric form is 100. The prefix 'milli-' denotes a factor of one-thousandth (1/1000) in the metric system.

Correctly Combine Value and Unit

Using the abbreviation for milliliters, combine the numeric value with the unit abbreviation. The correct expression is '100 ml,' where '100' represents the one hundred milliliters.

Key concepts

Abbreviations

Abbreviations are shortcuts for words that make writing and understanding easier. In the metric system, many measurement units like liters, meters, and grams have common abbreviations. This way, longer names are replaced with shorter, recognizable letters. For example, 'milliliters' is abbreviated to 'ml.' These abbreviations save space and time. When using them, make sure your reader understands what the abbreviation stands for. This is especially important in educational settings. Teachers often emphasize abbreviations since they are widely used in science, math, and everyday life.

Prefixes

Prefixes in the metric system help convey sizes of measurement by modifying the base unit. These prefixes represent powers of ten and make it simpler to express large or small numbers. For instance, the prefix 'milli-' means one-thousandth. This means that one milliliter (abbreviated as 'ml') is one-thousandth of a liter.

• 'Kilo-' indicates a thousand times the base unit, such as in kilogram (kg).
• 'Centi-' stands for one-hundredth, used in centimeters (cm).
• 'Milli-' as already mentioned, stands for one-thousandth.

Recognizing these prefixes helps in understanding numerical expressions in a logical and organized manner.

Milliliters

Milliliters are a unit of volume in the metric system often used to measure liquid quantities. The term 'milli-' signifies a thousandth, so one milliliter is one-thousandth of a liter. This unit is popular in contexts where small amounts of liquid are involved, such as in pharmaceuticals or cooking.

Imagine a medicine bottle; its capacity might be labeled in milliliters. If it reads '100 ml,' it means the bottle can hold 100 milliliters of liquid. By using the abbreviation 'ml,' it's simple to communicate without ambiguity. Understanding milliliters plays a critical role in numerous scientific and everyday activities.

Numeric Conversion

Numeric conversion involves changing numbers from one form to another, making it easier to comprehend and use. In the context of the metric system, numeric conversion translates verbal descriptions (like "one hundred milliliters") into numeric form ('100 ml').

This process is essential in calculations and measurements.

• By understanding numeric conversion, you can uniformly document measurements.
• It's important for ensuring accuracy and consistency across different situations.
• It assists in comparing quantities and executing mathematical processes.

Practicing numeric conversion helps you become efficient with numbers, which is advantageous in both academic and professional scenarios.
