The number that will occupy the denominator is 8

  • Given the expression, let's first;

Divide the two real numbers of the denominators between themselves:

-5/8 + 9/2

8 ÷ 2 = 4

With this number - we will multiply the terms of the second fraction with it:

-5/8 + 9/2

-5/8 + 9*4/2*4

-5/8 + 36/8

  • When the denominators are equal, we subtract or add the numerators and keep the denominators;

So we'll join these two fractions into one and then we'll do the sum:

-5/8 + 36/8

-5+36/8

31/8

Therefore, the value of this expression is 31/8, with denominator 8
