Look below

Step-by-step explanation:

1. Let's set up an equation...

45=n%90

45=n/100*90

45=9n/10

Multiply both sides by 10...

450=9n

Divide both sides by 9

n=50

50%

2. Let's set up an equation...

30=50%n

30=50/100*n

30=1/2*n

30=n/2

Multiply both sides by 2

n=60

60

Answer 2

1. n = 50

45 is 50% of 90.

2. n = 60

30 is 50% of 60.
