ii. 39 + 700.65

iii. 40 + 27.7 + 2.451

ii. 632.24 – 97.45

iii. 200.005 – 17.186

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

= 42.365 km

Distance travelled in car = 12 km 460 m

= 12 km + \(\frac { 460 }{ 1000 }\) km

= 12 km + 0.460 km

= 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

= 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

Cost of 1 m of cloth = Rs 120

∴ Cost of 4.05 m of cloth = 4.05 x 120

∴ 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

= 1.75 kg

∴ Weight of watermelon left = Total weight of watermelon – Weight of watermelon given to children

= 4.25 kg – 1.75 kg

= 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.

= 30.6 km per hr.

∴ Anita should reduce her speed by 30.6 km per hour to be within the speed limit.
