yes it is easy what u all have to do is to check that by which number or fraction is the equation being divided or multiplied, here in a it is multiplied by 10 so it will be 2 in b it is being divided by 100 or multiplied by 1/100 both are same so b will be 340 in first blank and in second it will be 0.034 in c it is being divided by 10 so in first blank it will be 85700 and in second it will be 857 and in third it will be 0.857 in d it is being multiplied by 10 so in first blank it will be 44400 in second it will be 444000 and in third it will be 4440000 in e it is... in the first blank it will be multiplied by 1/100 and then in second blank it will be multiplied by 100 so first blank will be 0.095 and second will be 9500000 and third blank will be 950000000
