Lius has 5 over 8 quart of grape juice he pours the same amount in each 5 glasses which equation represents the fraction of a quart of grape juice n that is in each glass

So we have to divide 5/8 into 5 equal segments.

5 5

- - : - - -

8 1

in order to divide fractions we need to flip the second fraction and change the sign from a divition sign to a multiplication sign

5 1 5

- - * - - - = - - -

8 5 40

now we just simplify 5/40 is equal to 1/8

each glass gets 1/8 of a quart
