First you need to understand that adding zeroes to the right of a decimal or the left of a whole number does not change the value. 

Maya's dog: 9.40
Eric's dog: 9.27

I can tell by looking at the numbers which one is greater, but here's a trick. 
 
9.27 - 9.40 = -0.13 
Since the answer to that equation we did was negative, that means that 9.27 is less than 9.40, we can double check this by doing:

9.40 - 9.27 = 0.13
That is a positive number, which means that 9.40 is greater. 

The answer is B.

Hope this helped! If you have anymore questions or don't understand, please comment on my profile or DM me. :)

(m+11n)^2=(m+11n)(m+11n)=m^2+11mn+11mn+121n^2=m^2+22mn×121n^2 for example; use foil: (a+b)(a+b)first. a^2outside. abinside. ablast. b^2
