#### About Class 6 Maths Chapter 8

In 6 Maths Chapter 8 Decimals, we will study various conversion into decimals. We will also learn about tenths, hundredths, etc., places in a decimal number. Place value chart using decimal is also important in this chapter. In the place value system as we go from left to right, at every step the multiplying factor becomes 1/10 of the previous factor. Comparison of number will also learnt here in this chapter.
Let us now compare the numbers 92.44 and 92.4.
In this case , we first compare the whole part.
We see that the whole part for both the numbers is 92 and, hence, equal.
We, however, know that the two numbers are not equal. So, we now compare the tenth part.
We find that for 92.44 and 92.4, the tenth part is also equal, then we compare the hundredth part.
Now the hundredth part of the first number is 4 whereas the second number is not given so, it is 0.
Hence, 92.44 is greater than 92.4.

Naresh walked 2 km 35 m in the morning and 1 km 7 m in the evening. How much distance did he walk in all?
Distance travelled in morning
= 2 km 35 m
= 2.035 km

Distance travelled in evening
= 1 km 7 m
= 1.007 km

Total distance travelled
= 2.035 + 1.007
= 3.042 km

Therefore, the total distance travelled by Naresh is 3.042 km.

Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m by foot in order to reach her school. How far is her school from her residence?
Distance travelled by bus
= 15 km 268 m
= 15.268 km

Distance travelled by car
= 7 km 7 m
= 7.007 km

Distance travelled on foot
= 500 m
= 0.500 km

Total distance travelled
= 15.268 + 7.007 + 0.500
= 22.775 km

Therefore, total distance travelled by Sunita is 22.775 km.

Ravi purchases 5 kg 400 g rice, 2 kg 20 g sugar and 10 kg 850 g flour. Find the total weight of his purchases.
Weight of Rice
= 5 kg 400 g
= 5.400 kg

Weight of Sugar
= 2 kg 20 g
= 2.020 kg

Weight of Flour
= 10 kg 850 g
= 10.850 kg

Total weight
= 5.400 + 2.020 + 10.850
= 18.270 kg

Therefore, the total weight of Ravi’s purchase = 18.270 kg.

नमिता प्रतिदिन 20 किमी 50 मी की दूरी तय करती है। इसमें से 10 किमी 200 मी दूरी वह बस द्वारा तय करती है और शेष ऑटो-रिक्शा द्वारा। नमिता ऑटो-रिक्शा द्वारा कितनी दूरी तय करती है?
कुल तय दूरी
= 20 किमी 50 मी
= 20.050 किमी

बस द्वारा तय दूरी
= 10 किमी 200 मी
= 10.200 किमी

इसलिए, ऑटो-रिक्शा द्वारा तय दूरी
= 20.050 किमी – 10.200 किमी
= 9.850 किमी

अतः, नमिता ऑटो-रिक्शा द्वारा 9.850 किमी की दूरी तय करती है।

आकाश 10 किग्रा सब्जी खरीदता है जिसमें से 3 किग्रा 500 ग्रा प्याज, 2 किग्रा 75 ग्रा टमाटर और शेष आलू हैं। आलू का वजन ज्ञात कीजिए।
सब्जी का कुल भार
= 10.000 किग्रा

प्याज का भार
= 3 किग्रा 500 ग्रा
= 3.500 किग्रा

टमाटर का भार
= 2 किग्रा 75 ग्रा
= 2.075 किग्रा

प्याज और टमाटर का कुल भार
= 3.500 किग्रा + 2.075 किग्रा
= 5.575 किग्रा

इसलिए, आलू का भार
= 10.000 किग्रा – 5.575 किग्रा
= 4.425 किग्रा

अतः, आलू का वजन 4.425 किग्रा है।
