Answer 1

We have to arrange increasing number of significant figures of 0.002600, 2.6000, 2.6 , 0.260

Solution : no of significant figures in 0.002600 = 4

no of significant figures in 2.6000 = 5

no of significant figures in 2.6 = 2

no of significant figures in 0.260 = 3

so, increasing order of significant figures would be 2 < 3 < 4 < 5

i.e., 2.6 < 0.260 < 0.002600 < 2.6000
