5/4Ⅹ+5/6Ⅹ=25

5/4Ⅹ+5/6Ⅹ=25 25/12x=25 x=25÷25/12 x=12

解如图。

原式=5/3×4/3×3/5×7/4×5/7×(-2/3) =-(5/3×3/5)×(4/3×2/3)×(7/4×5/7) =-1×8/9×5/4 =-10/9。

6x5分之4是(24/5) 6x4/5 =24/5(或4.8)

能把题拍下来么

42x(6/5十3/1一7/4) 分子分母全写反了 应该是 =42x(5/6十1/3一4/7) =42*5/6+42*1/3-42*4/7 =35+14-24 =49-24 =25 满意奥

4/5x=6.2-1.2 x=5÷4/5 x=5×5/4 x=25/4 x=6又1/4

(2/3+X)除以5/4=5/6 也就是 (2/3+X)×4/5=5/6 2/3×4/5+4/5X=5/6 4/5X=5/6-8/15 4/5X=25/30-16/30 4/5X=9/30 X=9/30÷4/5 X=9/30×5/4 X=9/24

4.25+5/6-(5/6-3/4) =4+1/4+3/4+(5/6-5/6) =4+1 =5
