Explanation:

Step1: Convert decimals to percentages

Multiply decimal by 100, add % sign.

• $0.064 \times 100 = 6.4\%$
• $6 \times 100 = 600\%$
• $0.375 \times 100 = 37.5\%$
• $2.25 \times 100 = 225\%$
• $0.09 \times 100 = 9\%$

Step2: Convert percentages to decimals

Divide percentage by 100, remove % sign; note: $3,264\%$ is $3264\%$.

• $4\% \div 100 = 0.04$
• $3264\% \div 100 = 32.64$
• $0.05\% \div 100 = 0.0005$
• $7.5\% \div 100 = 0.075$
• $1.003\% \div 100 = 0.01003$
