The metric ruler is divided into which units?
Correct Answer
B. Millimeters and centimeters
Explanation
The metric ruler is divided into millimeters and centimeters. Millimeters are smaller units of measurement, with each centimeter being divided into 10 millimeters. Centimeters are larger units, with each centimeter representing one-tenth of a meter. This division allows for precise measurements in the metric system, which is widely used in many countries around the world.
2.
The standard ruler is divided into which units?
Correct Answer
A. Inches and feet
Explanation
The standard ruler is divided into inches and feet. Inches are used for smaller measurements, while feet are used for larger measurements. This allows for precise measurements in both small and large scales.
3.
A millimeter is what part of a centimeter?
Correct Answer
A. 1/10
Explanation
A millimeter is a unit of length in the metric system. It is equal to one thousandth of a meter. On the other hand, a centimeter is equal to one hundredth of a meter. Therefore, to find out what part of a centimeter a millimeter is, we need to divide the value of a millimeter by the value of a centimeter. Dividing 1 millimeter by 1 centimeter gives us 1/10, which means that a millimeter is one-tenth or 1/10th of a centimeter.

Which scale is divided into 10, 20, 30, 40, 50, or 60 parts?
Correct Answer
B. Engineer's Scale
Explanation
An engineer's scale is divided into 10, 20, 30, 40, 50, or 60 parts. This scale is commonly used by engineers and architects to measure and draw accurately scaled diagrams and plans. It allows for precise measurements and calculations in engineering and construction projects.
10.
Which scale is divided into fractions of an inch that equals a foot.
Correct Answer
A. Architect's Scale
Explanation
The correct answer is Architect's Scale. An architect's scale is a specialized ruler used by architects and designers to make accurate measurements on blueprints and scaled drawings. It is divided into fractions of an inch that represent a foot. This allows architects to easily convert measurements on paper to the actual dimensions of a building or structure. An engineer's scale is also used for measuring, but it is divided differently and is typically used for more technical and precise measurements. A standard ruler, on the other hand, does not have the specific divisions required for measuring in feet and is not commonly used in architectural or engineering work.
