Correct Answer: D
Solution :
\[1.8+16.3\,+72.985\,\] \[\begin{align} & =0.1800 \\ & \,\,\,\,\,\underline{16.300} \\ & \,\,\,\,\underline{72.985} \\ \end{align}\] B: 27.091 ? 32.05 +19.05 = 27.091 + 19.05 ? 32.05 27.091 + 19.05 \[\begin{align} & =27.091 \\ & \,\,\,\,\,\underline{19.050} \\ & \,\,\,\,\underline{46.141} \\ \end{align}\] 46.141 ? 32.05 \[\begin{align} & =46.141 \\ & \,\,\,\,\,\underline{32.050} \\ & \,\,\,\,\underline{14.091\,\,} \\ \end{align}\] C: 0.5 + 12.56 + 0.003 \[\begin{align} & =00.500 \\ & \,\,\,\,\,\underline{+12.560} \\ & \,\,\,\,\underline{+00.003\,\,} \\ & \,\,\,\,\,\,\underline{13.063\,\,\,} \\ \end{align}\] D: Decimal forms of \[\frac{7}{100},\,\frac{124}{1000}\] and \[\frac{1956}{100}\] are 0.07, 0. 124 and 19.56 respectively. Their sum = 00.070 \[\begin{align} & \,\,\,\,\,\underline{+00.124} \\ & \,\,\,\,\underline{+19.560\,\,} \\ & \,\,\,\,\,\,\underline{19.754\,\,\,} \\ \end{align}\]
