C would be the answer I think
Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps
Both the numerator and denominator are divisible by 4, meaning that when they are both divided by this number they wll be in their simplest form.
e.g. 8/4=2 and 20/4=5
Therefore the simplest form is 2/5
