Question

2 wholes and 3/4 + 3/? = 2 wholes and 5/8

Answer 1

let's write it first:

2+$\frac{3}{4}$+$\frac{3}{x}$=2 $\frac{5}{8}$

let's substract 2 from both sides

$\frac{3}{4}$+$\frac{3}{x}$=$\frac{5}{8}$

and let's substract $\frac{3}{4}$ from both sides too

$\frac{3}{x}$=$\frac{5}{8}$-$\frac{3}{4}$

this is

$\frac{3}{x}$=$\frac{5}{8}$-$\frac{6}{8}$
$\frac{3}{x}$=$\frac{-1}{8}$

let's multiply by x:
3=$\frac{-1x}{8}$

and by8:
24=-x
x=24
that means that the question mark is -24!!!!
