Answer:
0.66 > 13/20 > 64/100 > 60% > 0.066 > 6%Step-by-step explanation:
To convert fraction or decimal to percentage, we need to multiply it by 100%. So,
64/100 × 100% = 64%
0.66 × 100% = 66%
0.066 × 100% = 6.6%
13/20 × 100% = 65%
Thus, it can be arranged in descending order is :
0.66 > 13/20 > 64/100 > 60% > 0.066 > 6%
