Х×80=640 4200÷Х=6 Х÷50=500

Answer 1

1) 80 x = 640
x = 640/80
x = 8
80*8 = 640
640 = 640

2) 4200/x = 6
x = 4200/6
x = 700
4200/ 700 = 6
6=6

3) x/50 = 500
x = 500*50
x = 25000
25000/50 = 500
500=500

Answer 2

X*80=640
X =640÷80
X=8
------------------
8*80=640
640=640

4200÷X=6
X=4200÷6
X=700
-------------------
4200÷700=6
6=6

X÷50=500
X=500*50
X=25000
------------
25000÷50=500
500=500
