How do you order the numbers 0.64, start fraction 2 over 3 end fraction , 65%, and start fraction 7 over 10 end fraction from least to greatest?

The numbers are : 0.64, 2/3, 65%, 7/10
Now, 2/3 = 0.66
And 7/10 = 0.7
65% = 65/100 = 0.65

Now, we write the numbers in ascending order i.e. from smaller number to bigger number:

0.64 < 0.65 < 0.66 < 0.70

Therefore, the numbers from least to greatest are :

0.64, 65%, 2/3, 7/10
