Let us see the solution for this one.

420 : 96

= 210: 48 [ Dividing both numerator & denominator by 2]

= 105: 24 [ Again dividing both numerator & denominator by 2]

= 35:8 [ Dividing both numerator & denominator by 3]

So, the simplest ratio is 35: 8

Hope this has helped you to some extent. Now solve the other related problems with your friends.

HI  YOU NEED TO FIND THE HIGHEST COMMON DENOMINATOR   FOR   420  AND  96

TRY  2  FIRST   THAT GIVES   210  AND  48  TRY 2 AGAIN  THIS GIVES  105  AND  24 

2 WILL NOT GO INTO ODD NUMBER THEREFORE TRY 3    THAT GIVES  35  AND 8

THEREFORE  420 : 96  IN SIMPLE TERMS IS  35 : 8 

THIS  THEN BREAKS DOWN INTO     35 = (7X5)   :   8 = ( 2X2X2)

I HOPE THIS HAS HELPED YOU UNDERSTAND HOW TO SIMPLIFY  RATIO'S
