Respuesta :

It's 4y because it is multiplying, meaning it does not matter the order of the numbers and variables.
We have the following expression:
 3a. 4y. 5
 Using commutative property we have:
 5 . 3a. 4y
 Therefore we have that the corresponding equality is:
 3a. 4y. 5 = 5 3a. 4y
 We now observe the expression given in the problem:
 3a. 4y. 5 = 5 3a
 Comparing with the obtained expression, it is observed that the missing term is:
 4y
 Answer:
 The missing for the quantity to be true is:
