Which of the following sets of numbers is in order from least to greatest?
a. 40 percent , 0.55,3/20, 2/3
b. 2/3, 3/20,40 percent,0.55
c. 3/20,40 percent,0.55,2/3
d. 0.55,3/20,2/3,40 percent

The answer is C. 3/20, 40 percent, 0.55, 2/3

Step-by-step explanation:

Just change it all to decimals.

3/20 = 15% = 0.15

40% = 0.40

0.55 is already a decimal

2/3 ≠ 0.66

If you want to know how to change a fraction to a percent:

Divide the numerator by the denominator. Then multiply the answer by 100.

Ex:  The fraction is 4/50.

       Divide 4 by 50 (4÷50= 0.08)

       Then multiply (0.08 x 100)

       You get 8.  That means that 4 is 8% of 50.
