Question 1.
In the table below, write the place value of each of the digits in the number 378.025.

Place Hundreds Tens Units Tenths Hundredths Thousandths
100 10 1 \(\frac { 1 }{ 10 }\) \(\frac { 1 }{ 100 }\) \(\frac { 1 }{ 1000 }\)
Digit 3 7 8 0 2 5
Place value 300 \(\frac { 0 }{ 10 }=0\) \(\frac { 5 }{ 1000 }\)
= 0.005

Solution:

Place Hundreds Tens Units Tenths Hundredths Thousandths
100 10 1 \(\frac { 1 }{ 10 }\) \(\frac { 1 }{ 100 }\) \(\frac { 1 }{ 1000 }\)
Digit 3 7 8 0 2 5
Place value 300 7 × 10 = 70 8 × 1 = 8 \(\frac { 0 }{ 10 }=0\) \(\frac { 2 }{ 100 }\)
= 0.02
\(\frac { 5 }{ 1000 }\)
= 0.005

Question 4.
Avinash traveled 42 km 365 m by bus, 12 km 460 in by car and walked 640 m. How many kilometers did he travel altogether? (Write your answer in decimal fractions)
Solution:
Distance traveled in bus = 42 km 365 m
= 42 km + \(\frac { 365 }{ 1000 }\) km
= 42 km + 0.365 km
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 7
= 42.365 km
Distance travelled in car = 12 km 460 m
= 12 km + \(\frac { 460 }{ 1000 }\) km
= 12 km + 0.460 km
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 8
= 12.460 km
Distance walked = 640 m
= \(\frac { 640 }{ 1000 }\) = 0.640 km
∴ Total distance travelled = Distance travelled in bus + Distance travelled in car + Distance walked
= 42.365 + 12.460 + 0.640
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 9
= 55.465 km
∴ Distance travelled altogether by Avinash is 55.465 km.

Question 5.
Ayesha bought 1.80 m of cloth for her salwaar and 2.25 for her kurta. If the cloth costs Rs 120 per metre, how much must she pay the shopkeeper?
Solution:
Total length of cloth bought = 1.80 m + 2.25 m
= 4.05 m
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 10
Cost of 1 m of cloth = Rs 120
∴ Cost of 4.05 m of cloth = 4.05 x 120
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 11
∴ Amount to be paid to the shopkeeper is Rs 486.

Question 6.
Sujata bought a watermelon weighing 4.25 kg and gave 1 kg 750 g to the children in her neighbourhood. How much of it does she have left?
Solution:
Total weight of watermelon = 4.25 kg
Weight of watermelon given to children = 1 kg 750 g
= 1 kg + \(\frac { 750 }{ 1000 }\) kg
= 1 kg + 0.75 kg
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 12
= 1.75 kg
∴ Weight of watermelon left = Total weight of watermelon – Weight of watermelon given to children
= 4.25 kg – 1.75 kg
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 13
= 2.5 kg
∴ Weight of watermelon left with Sujata is 2.5 kg.

Question 7.
Anita was driving at a speed of 85.6 km per hour. The road had a speed limit of 55 km per hour. By how much should she reduce her speed to be within the speed limit?
Solution:
Speed at which Anita is driving = 85.6 km per hr.
Speed limit = 55 km per hr.
∴ Anita should reduce her speed by 85.6 km per hr – 55 km per hr.
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 14 14
= 30.6 km per hr.
∴ Anita should reduce her speed by 30.6 km per hour to be within the speed limit.
