Answer 2

Respuesta:
1) x*1/6=3/4
x = 3/4/1/6
x = 9/2
2) x*2 1/2=3/8
x* 5/2 = 3/8
x = 3/8/5/2
x = 3/20
3) 1/4*x=9
x = 9/1/4
x = 36
4) 2/3*x=8
x = 8/2/3
x = 12
5) 2/9*x= 5/6
x = 5/6/2/9
x = 15/4
6) 1/3*x = 4/9
x = 4/9/1/3
x = 4/3
7) 3 1/4*x= 2 1/2
13/4*x = 5/2
x = 5/2/13/4
x = 10/13
8) 3*x= 1/4
x = 1/4/3
x = 1/12
9) 2 7/9*x = 4/15
25/9*x = 4/15
x = 4/15/25/9
x = 12/125
10) 5 1/2*x= 3/8
11/2*x = 3/8
x = 3/8/11/2
x = 3/44
