The metric ruler is divided into which units?
- A.
  
  Inches and feet
- B.
  
  Millimeters and centimeters
- C.
  
  Fractions and decimals
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.

A millimeter is what part of a centimeter?
- A.
  
  1/10
- B.
  
  1/100
- C.
  
  1/1000
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.

  900
- B.
  
  1200
- C.
  
  300
Correct Answer
A. 900

Explanation
Multiply $100 x 12 rooms = $1200
Multiply $25 x 12 rooms = $300
Subtract $300 from $ 1200: 1200-300 = $900

Which scale is divided into 10, 20, 30, 40, 50, or 60 parts?
- A.
  
  Architect's scale
- B.
  
  Engineer's Scale
- C.
  
  Metric Ruler
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.

Which scale is divided into fractions of an inch that equals a foot.
- A.
  
  Architect's Scale
- B.
  
  Engineer's Scale
- C.
  
  Standard Ruler
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.
