Question

Order from least to greatest: 2/3, 25%, 3/5, 0.40

Answer 1

Converting everything into percents make it a lot easier.
2/3 = 67%
25% = 25%
3/5 = 60%
0.40 = 40%

Now you can order away!
25%, 0.40, 3/5, 2/3

Answer 2

25%,0.40,
`(3)/(5)`,
`(2)/(3)`

Explanation:

`(2)/(3)`, 25%,
`(3)/(5)`, 0.40

25% , to remove % we divide by 100

25% is 25/100 = 0.25

`(2)/(3)` is equal to 0.666

`(3)/(5)` is equal to 0.6

We write the numbers in decimal form

0.666, 0.25, 0.6, 0.40

Now we arrange the numbers in order

0.25, 0.40, 0.6, 0.666

So the order becomes

25%,0.40,
`(3)/(5)`,
`(2)/(3)`
