Work: Calculate the value of equation (0.25+0.5+0.75+1+1.25-1.5-1.75)÷(5×0.3-1.3) .
Question type: Mathematical calculation
Solution:
(0.25+0.5+0.75+1+1.25-1.5-1.75)÷(5×0.3-1.3)
=0.5÷(5×0.3-1.3)
=0.5÷0.2
=2.5 Answer:(0.25+0.5+0.75+1+1.25-1.5-1.75)÷(5×0.3-1.3)=2.5Your problem has not been solved here? Please go to the Hot Problems section!
