7.2除以1.8再除以1.8(脱式计算)

25.2÷〔14.2÷(14.2-(7.2+2.8))〕 =25.2÷〔14.2÷(14.2-10)〕 =25.2÷〔14.2÷4.2〕 =25.2×4.2÷14.2 =105.84÷14.2 =7.45 你好,本题已解答,如果满意 请点右下角“采纳答案”。

62除以4乘2 =15点5乘2 =31

7.2×1.8+5.9 =12.96+5.9 =18.86 你好,本题已解答,如果满意 请点右下角“采纳答案”。

7/9÷2/3+2/9 =7/9×3/2+2/9 =7/6+2/9 =21/18+4/18 =25/18

13.7×2.9+71×1.37 =13.7×2.9+7.1×10×1.37 =13.7×(2.9+7.1) =13.7×10 =137

(1)5.07-(3.07-1.8)=5.07-3.07+1.8=2+1.8=3.8(2)58.6×7.2+245×5835=58.6×7.2+2.8×58.6=58.6×(7.2+2.8)=58.6×10=586(3)(12+16+18)×0.24=12×0.24+16×0.24+18×0.24=0.12+0.04+0.03=0.19(4)416-1.65-1.35=416-(1.65+1.35)=416-3=116

解:依题意得算式, 7.2÷1.8×(3.4-2.9) =4×0.5 =2 7.2÷1.8×(3.4-2.9)=2

(九又2/7-7又2/9)÷(5/9+5/9) =2又63分之4÷10/9 =130/63×9/10 =13/7 =1又7分之6
