$43/8$

$7/8+4 1/2$

Here, $4 1/2$ is nothing other than $4+1/2$ .

The calculation goes this.....

$7/8+4 1/2$

$=7/8+(4+1/2)$
$=7/8+(4(2)+1)/2$

$=7/8+(8+1)/2$

$=7/8+9/2$

$=7/8+(9(4))/(2(4))$

$=7/8+36/8=(7+36)/8=43/8$

$= 5 3/8$

We can work with the mixed numbers. The values to work with are smaller than if we change to improper fractions.

Add the whole numbers first: then find common denominator

$7/8 + 4 1/2$

$= 4 (?+?)/8$

Make equivalent fractions

$= 4 (7+4)/8" "larr (1/2 = 4/8)$

$= 4 11/8$

$= 4+1 3/8" "larr 11/8 = (8+3)/8$

$= 5 3/8$
