Under ratio and proportion, there are a couple of ways you can use aside from using words to establish the relationship between 2 numbers.
One would be in a fraction form where "3 to 10" can be written as "3/10", or using a colon between the two numbers, where it would be written as "3:10". It is necessary to understand that these forms all mean the same, even if they look really different.
The 1st choice, the third and the fifth are correct
because 26/9 = 3
and 12/4 = 3
and 21/7 = 3
Minus 1 on both sides
Divide by 3 on both sides
C 5 > 7/3
