Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1
