The answer would be 77.
If you make the ratios into a proportion it would be
7/5= x/55
You have to figure out what times 5 equals 55, which is 11
Whatever you do to the bottom half you have to do to the top half
Since you did times 11, you have ti multiply 11 by 7, which is 77

77 will be your answer

5 x 11 = 55 so
7 x 11 = 77

since these are ratios, what you do to the right, you do to the left, and vice versa

hope this helps
