## FAQs on CBSE Class 6 Maths Formulas

Q1: What are the important properties of proportion?

A1: The following are the important properties of proportion:

• Addendo – If a : b = c : d, then a + c : b + d

• Subtrahend – If a : b = c : d, then a – c : b – d

• Dividendo – If a : b = c : d, then a – b : b = c – d : d

• Componendo – If a : b = c : d, then a + b : b = c+d : d

• Alternendo – If a : b = c : d, then a : c = b: d

• Invertendo – If a : b = c : d, then b : a = d : c

• Componendo and dividendo – If a : b = c : d, then a + b : a – b = c + d : c – d

Q2: What are the Natural Numbers and Whole Numbers Properties?

A2: The various properties of Natural numbers and Whole numbers are as follows:

• When two natural numbers are added, the result is a natural number.

Eg: 34+145 = 179

• Similarly, when two whole numbers are added, the result is a whole number.

Eg: 6+10= 16

• Subtraction Property

• The subtraction of two natural numbers may or may not result in a natural number.

• Eg: 5 –12 = -9 is not natural number

• But 11– 5 = 6 is a natural number

• The subtraction of two whole numbers may or may not result in a whole number.

• Multiplication Property

• Multiplication of two natural numbers always results in a natural number

• Eg: 12 X 6 = 72 is a natural number

• Multiplication of two whole numbers always results in a whole number

• Ex: 14 X 0 = is a whole number, where 4 and 0 are also whole numbers.

• Division Property

• Division of two natural numbers may always not always result in a natural number.

• Division of two whole numbers may always not always result in a whole number.

This is because if the result is in fraction or decimal, then they are not considered as natural or whole numbers.

Eg: 4/2 = 2 is natural as well as the whole number.

But 5/2 = 2.5 is neither natural nor the whole number.

Q3: What are the important formulas of mensuration?

A3: Some important formulas of mensuration are as follows:

• Square -  Area -  (side)2 , Perimeter - 4 x side

• Triangle - Area - ½ ( b x h ) , Perimeter - Sum of all sides

• Rectangle - Area - length x breadth , Perimeter - 2 * ( length + breadth )

• Circle - Area - πr2 , Perimeter - 2πr

Q4: What is the order of operations in algebra?

A4: The order of operation in algebra is given as follows:

• First preference is given to all the operations inside the brackets.

• Then all the operations on roots and exponents must be performed.

• This is followed by the division and multiplication operations moving from left to right.

• Then all the addition and subtraction operations must be performed from left to right.

NOTE: Students must ensure that all the operations must be performed according to BODMAS: Brackets, Of( Multiplication), Division, Multiplication, Addition and Subtraction. SHARE TWEET SHARE SUBSCRIBE
