Question

If the school bags of Neelam and Garima weigh 6 kg 80 g and 5 kg 265 g respectively, whose bag is heavier and by how much?

Answer 1

Weight of Neelam's school bag =   6080 g {Converting into grams: 6 kg + 80 g = (6000 + 80) g = 6080 g}
Weight of Garima's school bag =  −5265 g  {Converting into grams: 5 kg + 265 g = (5000 + 265)g = 5265 g}
Difference of the weights of bags =  815 g
Thus, the weight of Neelam's school bag is more than that of Garima's school bag by 815 grams, i.e. by 0.815 kg.
