You can put this solution on YOUR website! Since 1 minute = 60 seconds, this means that 7 minutes = 420 seconds (multiply both sides by 7)

simplify:7mins/400sec
----
convert to seconds:
[7min/400sec][60 sec/1 min]
=
[420 sec/400 sec]
==============================
OR
convert to minutes:
[7 min/400sec][60 sec/1 min]
[7 min/1 min][60 sec/400 sec
= (3/20)[7 min/1 min]
---
= [21 min/20 min]
===========================
