Answer 1

Answer:

(3×1):(4*y)

Step-by-step explanation:

45:60=3:4

x²:x²=1

(3×1):(4*y)

Answer 2

Answer:

$\sf \dfrac{3}{4y}$

Step-by-step explanation:

Simplify:

  45 = 5 * 3 * 3

  60 = 5 * 3 * 2 * 2

GCF = 5*3 = 15

           $\sf \dfrac{45x^2}{60x^2y}=\dfrac{45}{60y}$

                     $\sf =\dfrac{45 \div 15}{60y \div 15}\\\\= \dfrac{3}{4y}$
