To find the rule of translation, find the change of corresponding coordinates. In this graph, for example see how A is moved to A': three units to the right, then two units down. A(-4,3)+(3,-2)=A'(-1,1). This applies to the whole shape, and is the rule of translation.
I think as in whole numbers in numerator it should be in improper fraction since 4.5= 4wholes and 5/10 it's 9/2?
and 2.5 in mixed fraction is 2 wholes 5/10 in improper is 5/2
unless you say mixed fraction is okay to leave if for the answer than it's respectively 4wholes 1/2 and 2wholes 1/2?
I'm not sure but I learnt this in my school and it goes like this
The factors of 13 are 1 and 13 .
13 is a "prime" number.
