2.3 m + 27 cm +9.3 mm - 3.2 dm

Convert all to m:
= 2.3m + 0.27m + 0.0093m + 0.32 m

Add them up:
= 2.8993m

Answer: 2.8993m

change all the numbers into same unit.
●m (x10)→dm(x10)→cm(x10)→mm
●mm(÷10)→cm(÷10)→dm(÷10)→m

27cm÷100=0.27M
9.3mm÷10=0.93cm÷100=0.0093M
3.2dm÷10=0.32m
the answer is 2.8993
