Assuming your shell splits words on white space characters:

Code:
$ v="1 2 3 4" t="a b c d"; set -- $t
$ for v in $v;do printf "%s/%s\n" "$v" "$1";shift;done
1/a
2/b
3/c
4/d

  rt=${t##?}
  ct=${t%"$rt"}

  printf "%s/%s\n" "$cv" "$ct"

  v=${rv#?}

You could use arrays to...

t=(`echo "1 2 3 4"`)
v=(`echo "a b c d"`)

for index in "${t[@]}"; do
echo $index/${v[$index-1]}
done

Note that arrays are not available in all POSIX shells.

Why are you using echo and command substitution?

What's wrong with:

Code:
t=( 1 2 3 4 )
v=( a b c d )

for index in "${t[@]}"; do
echo $index/${v[$index-1]}
done

That was part of the original posters requirements.

Where do you see that? There's no mention of either in the original post.
