Initially we can display the ratio as:
72:36.
Both numbers are divisible by 36 as that is your highest common factor for both.
72/36 = 2
36/36 = 1
After simplification, we get the answer of 2:1
<span>Let the number of chairs in a row be x, then the total number of chairs is 9x + 3 = 7x + 19. i.e. 9x + 3 = 7x + 19; 9x - 7x = 19 - 3; 2x = 16 x = 16/2 = 8. Thus there are 8 chairs in each row. Therefore, the total number of chairs is given by 9(8) + 3 = 72 + 3 = 75.I hope that my answer is helpful! Let me know if you need something more :)</span>
