Good evening
7/.. = 2/16
To find the missing number we gonna replace the missing number by x
7/x = 2/16
now use the cross multiply
(7)(16) = (2)(x)
112 = 2x
Now flip
2x = 112
Divide both sides by 2
2x/2 = 112/2
x= 56
The missing number is 56
Now if you want to check the answer just replace the blank space by 56
7/56 = 2/16
Now divide 7 by 56 and divide 2 by 16
7/56= 0.125
2/16= 0.125
SO The answer is good :)
I hope that's help:)
