Esta es una pregunta de matemáticas?
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
Answer:
3rd option
Step-by-step explanation:
Given
← factor numerator and denominator
= ← cancel (x - 3) on numerator / denominator
=
700
600
when two hours have passed sinces
600+ 50x=y
600+50(2)=700
