CBSE Class 6th ( VI) Mathematics Chapter 8. Decimals: Exercise 8.6 Solved

Things to remember...

  1. To understand the parts of one whole (i.e. a unit) we represent a unit by a block. One block divided into 10 equal parts means each part is 1/10 (one-tenth) of a unit. It can be written as 0.1 in decimal notation. The dot represents the decimal point and it comes between the units place and the tenths place.

CBSE Class 6th ( VI) Mathematics Chapter 3. Playing with Numbers: Exercise 3.7 Solved

1. Renu purchases two bags of fertiliser of weights 75 kg and 69 kg. Find the maximum value of weight which can measure the weight of the fertiliser exact number of times.

Answer:
The Highest Common Factor (HCF) of 75kg and 69kg by weight will be the maximum value of weight which can measure the weight of the fertiliser exact number of times. To find HCF first we have to find prime factorisation of given numbers by weight i.e. 75 and 69
