Answer 3

To solve the first equation, we can convert both mixed numbers to improper fractions:

7 4/5 = 39/5 2 3/5 = 13/5

Then we can divide 39/5 by 13/5:

(39/5) ÷ (13/5) = (39/5) x (5/13) = 3

Therefore, the solution to the first equation is 3.

To solve the second equation, we can cross-multiply:

(4 1/2) * y = (7/2) * (y)

Then we can simplify:

(4 1/2) * y = (7/2) * (y) 9/2 * y = 7/2 * y 2/2 * y = 0 y = 0

Therefore, the solution to the second equation is y = 0.

In summary:

7 4/5 : 2 3/5 = 3

4 1/2 : y = 0
