Question

三分之二加五分之二x等于十分之九解方程9/10-2/3=多少？

9/10-2/3等于多少

Answer 1

三分之二加五分之二x等于十分之九解方程
2/3+2/5 x=9/10.
2/5x=9/10-2/3.
2/5 x=27/30-20/30.
2/5 x=7/30.
X=7/12.

Answer 2

解方程：
三分之二加五分之二x等于十分之九
2/3+2/5x=9/10
2/5x=9/10-2/3
2/5x=27/30-20/30
2/5x=7/30
x=7/30×5/2
x=7/12

Answer 3

2/3+2/5X=9/10
2/5X=9/10-2/3
2/5X=27/30-20/30
2/5X=7/30
X=7/30×5/2
X=7/12

Answer 4

2/3+2x/5=9/10
2x/5=9/10-2/3
2x=9/2-10/3
x=9/4-5/3
x=27/12-20/12
x=7/12

9/10-2/3=27/30-20/30=7/30
