把下列算式改成文字题[(3+0.5)-2.7]/0.3(7.8-4.2)X(5.3-2.1)把下列算式改成文字题[(3+0.5)-2.7]/0.3(7.8-4.2)X(5.3-2.1)把下列算式改成文

把下列算式改成文字题[(3+0.5)-2.7]/0.3(7.8-4.2)X(5.3-2.1)
把下列算式改成文字题
[(3+0.5)-2.7]/0.3
(7.8-4.2)X(5.3-2.1)

把下列算式改成文字题[(3+0.5)-2.7]/0.3(7.8-4.2)X(5.3-2.1)
[(3+0.5)-2.7]/0.3
3与0.5的和减去2.7再除以0.3,商是多少?
(7.8-4.2)X(5.3-2.1)
7.8减4.2的差乘以5.3减2.1的差,积是多少?
