1.

Without actual division give decimal form of 219 by 750

Answer»

Sol:
15/4 + 5/40 = 15/4 + 1/8
                   = [(15x25) / (4x25)] + [(1 X 25/2) / (8 x 25/2)]
                   = (375/100) + [(25/2) / 100]
                   = (375/100) + (12.5/100)
                   = 3.75 + 0.125
                   = 3.875
