3、解方程 X-1/4X=2/3 X÷3/5=3/4 1/5X=25%
人气:452 ℃ 时间:2020-05-08 03:15:30
解答
X-1/4X=2/3
3x/4=2/3
x=8/9
X÷3/5=3/4
x=3/4×3/5
x=9/20
1/5X=25%
x=1.25
推荐
3、解方程、我要列式 X-1/4X=2/3 X÷3/5=3/4 1/5X=25%
解方程:①19-120%X=7 ②(1-25%)X=36 ③3/4X-50%X=17.5 ④8.5x+1.5=1000%
(1)6/7X=2/9÷2/3 (2)X÷1/12=4/5 (3)3/4X-1/5X=22/25
4x−1.50.5−5x−0.80.2=1.2−x0.1.
解方程:0.5(4x-1.5)-0.2(5x-0.8)=0.1(1.2-x)+3
改错:Noddles are popular in China.
