Answer:
[tex]\frac{1}{20}[/tex] more cheese in Sarah's dish than Amyn.
Step-by-step explanation:
To find this, we need to get the two fractions, [tex]\frac{2.5}{10}[/tex] and [tex]\frac{1.6}{8}[/tex] to a common denominator. The closest one is a multiple of 4 for [tex]\frac{2.5}{10}[/tex] and a multiple of 5 for [tex]\frac{1.6}{8}[/tex] .
This makes both fractions much more comparable, and we have
[tex]\frac{10}{40}[/tex] for Sarah's dish
[tex]\frac{8}{40}[/tex] for Amyn's dish.
Knowing Sarah has [tex]\frac{2}{40}[/tex]'s more cheese in her dish, we can still simplify, so after dividing 40 by 2, we get [tex]\frac{1}{20}[/tex], the simplest form of how much more cheese Sarah has in her dish than Amyn,
