He missed 6 for every 21 he attempted.
Step 1. Divide 21 by 6 to find how many he attempts for every goal he misses:
[tex]\frac{21}{6}=3.5[/tex]He attempts 3.5 for every goal he misses.
Step 2. Since he missed 14, we multiply 14 by 3.5 to find how many he attempted:
[tex]14\times3.5=49[/tex]Answer: 49
