Step-by-step explanation:

1. Let n be the number

18 = 45%n

Change to decimal

45%/100% = 0.45

18 = 0.45n

n = 18/0.45

n = 40

2. n = 135%(50)

Change to decimal

135%/100% = 1.35

n = 1.35(50)

n = 67.5

3. 125 = 25%n

Change to decimal

25%/100% = 0.25

125 = 0.25n

n = 125/0.25

n = 500

4. 5n = 1.6

n = 1.6/5

n = 0.32

Change to percentage

0.32(100%) = 32%

n = 32%

5. n = 18%(65)

Change to decimal

18%/100% = 0.18

n = 0.18(65)

n = 11.7
