So that we understand the value of the measurement number. A value of 5 does not tell you if it refering to distance, volume, or mass. If it is a distance whether it is about 5 feet, 5 inches, 5 miles, or 5 centimetes, 5 meters, 5 kilometers or anythinge else.
A measurement includes both a number and a unit to provide a quantitative value and context for what is being measured. The number indicates the amount or quantity being measured, while the unit specifies the scale or magnitude of the measurement. Without both components, the measurement lacks clarity and may be misunderstood or misinterpreted.
We need to know the "unit of measure" ( ie metre, gram etc) and the number of units.
ie 10 (No of Units) Metre (Unit of measure)

All measurements must consist of?
A unit of measurement, a number indicating the quantity, and a scale or reference to provide context.
What measurement must you make to find density of a sample of matter?
Two measurements are needed - you must find its mass and its volume. Density is mass divided by volume.
If there is a difference between a substance's atomic number and its atomic mass and which measure must be the larger number?
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
How can the number of significant figures in a measurement be increased without changing the measuring device?
To increase the number of significant figures in a measurement, you can estimate between the smallest markings on the measuring device. For example, if a device measures to the nearest 0.1 unit, you can estimate to the nearest 0.01 unit to increase the number of significant figures.
What conditions are necessary when measuring BMR?
When measuring Basal Metabolic Rate (BMR), it's important to ensure the individual is in a fasting state, both physically and mentally at rest, and has not engaged in any strenuous physical activity prior to the measurement. Additionally, the environment should be thermoneutral to prevent any external factors from influencing the metabolic rate measurement.

What two things must a measurement have?
a number and a unit
All measurements must consist of?

When a scientist is making a measurement what information must be included with the number?
The measurement units and the degree of precision (significant figures or margin of error).
A neutral with 15 protons must include what else?
15 Electrons. A charge-less (neutral) atom must have an equal number of both protons and electrons, otherwise it becomes an ion.
Why should probability always include a number?
Probability is a numerical value and there must bea number, not just include one.
What number is divisible by 3 and 7?
A number that is divisible by both 3 and 7 must be a multiple of their least common multiple, which is 21. Therefore, any number that is a multiple of 21 will be divisible by both 3 and 7. Examples of such numbers include 21, 42, 63, 84, and so on.
