Question

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?

Answer 1

Total weight of the watermelon = 4.25 kg

Weight of the watermelon given to the children = 1 kg 750 g
= 1 kg + 750 g
= 1 kg +`750/1000` kg
= 1 kg + 0.75 kg
= 1.75 kg

∴ Weight of the watermelon left with her
= Total weight of the watermelon − Weight of the watermelon given to the children
= 4.25 kg − 1.75 kg
= 2.5 kg

   3 12
   4. 2  5
 −1. 7  5  
   2. 5  0   

Thus, the weight of watermelon left with Sujata is 2.5 kg.
