Question

X : 7 = 23
729 : x = 81

x : 19 = 45

2852 : x = 23

x : 21 = 73

156 : x = 13

5 . x = 725

72.x= 3600

x.14=210

x.23=2323

3.x=624

25.x=1025

x.36 = 396

x.35=2170

Answer 1

x=7x23=161

x=729:81=9

x=19x45=855

x=2852:23=124

x=21x73=1533

x=156:13=12

x=725:5=145

x=3600:72=50

x=210:14=15

x=2323:23=101

x=624:3=208

x=1025:25=41

x=396:36=11

x=2170:35=62

Answer 2

x:7=23
x=23•7
x=161
729:x=81
x=729:81
x=9
x:19=45
x=45•19
x=855
2852:x=23
x=2852:23
x=124
x:21=73
x=21•73
x=1533
156:x=13
