Question

24-(5,418+8,05):(2,43+2,12)
6:0,25+23,5:0,5+0,15:30
0,04×2,15+0,005×0,12 rewite pojalusto

Answer 1

1. 5.418+8.05=13.468-4.55=2.96
2.43+2.12=4.55
24-2.96=21.04
2. 6÷0.25+23.5÷0.5+0.15÷30=71.005
6÷0.25=24
23.5÷0.5=47
0.15÷30=0.005
3.0.04×2.15+0.005×0.12=0.0866
0.04×2.15=0.086
0.005×0.12=0.0006
