(e) 0.75 + 10.425 + 2
(f) 280.69 + 25.2 + 38


Answer :

(a) 0.007 + 8.5 + 30.08
= 00.007 + 08.500 + 30.080 = 38.587
(b) 15 + 0.632 + 13.8
= 15.000 + 0.632 + 13.800= 29.432
(c) 27.076 + 0.55 + 0.004
= 27.076 + 0.550+ 0.004 =27.630
(d) 25.65 + 9.005 + 3.7
= 25.650 + 9.005 + 3.700 = 38.355
(e) 0.75 + 10.425 + 2
= 0.750 + 10.425 + 2.000 = 13.175
(f) 280.69 + 25.2 + 38
= 280.69 + 25.20 + 38.00 = 343.89
