Two plant shoots grow 0.68 metres and 1.275 metres. Enter their combined growth in metres.
Richtige Antwort
1.955
Erklärung
Padding the shorter decimal gives 0.680 + 1.275 = 1.955, so the combined growth is 1.955 metres. A sum such as 1.343 would come from right-aligning the final digits rather than aligning the decimal points.
