c. 150% of 50 g. 1% of 1,000
d. 20% of 800

Explanation:

Step1: Convert % to decimal, calculate A

$120\% \times 100 = 1.2 \times 100 = 120$

Step2: Convert % to decimal, calculate B

$50\% \times 150 = 0.5 \times 150 = 75$

Step3: Convert % to decimal, calculate C

$150\% \times 50 = 1.5 \times 50 = 75$

Step4: Convert % to decimal, calculate D

$20\% \times 800 = 0.2 \times 800 = 160$

Step5: Convert % to decimal, calculate E

$200\% \times 30 = 2 \times 30 = 60$

Step6: Convert % to decimal, calculate F

$500\% \times 400 = 5 \times 400 = 2000$

Step7: Convert % to decimal, calculate G

$1\% \times 1000 = 0.01 \times 1000 = 10$

Step8: Compare values to 100
