x:8/11=11/3
x=11/3X8/11
x=8/3
b) 2/5:x=1/4
x=2/5:1/4
x=8/5
c)4/5+5/7:x=1/6=?
ai tích mình tích lại
a) x = 88/33=8/3
b) x = 8/5
c) x = 150/133
a) x / 8/11 = 11/3
x = 11/3 * 8/11
x = 88/33
b) 2/5 / x = 1/4
x = 2/5 / 1/4
x = 8/5
c) 4/5 + 5/7 / x = 1/6
53/35 / x = 1/6
x = 53/35 / 1/6
x = 318/35
Ai k mk mk k lại
