0.2=1/5?

0.9=9/10

0.80=4/5?

0.55=11/20

All are correct. :-)

1.5=1/2

0.5=1/2

0.06=3/50

0.75=3/4

2.25=1/4

0.60=3/5

These two are wrong. You forgot the whole numbers.

1.5=1/2

2.25=1/4

0.60=3/5

0.015=3/200

0.05=1/200

To check if the given decimal numbers are equal to their corresponding fractions, you need to convert the fractions to decimals and compare the results.

Let's check each of the given examples:

1. Is 0.2 equal to 1/5?
To convert 1/5 into a decimal, divide 1 by 5: 1 ÷ 5 = 0.2. Since 0.2 is equal to 0.2, the statement is true.

2. Is 0.9 equal to 9/10?
To convert 9/10 into a decimal, divide 9 by 10: 9 ÷ 10 = 0.9. Since 0.9 is equal to 0.9, the statement is true.

3. Is 0.80 equal to 4/5?
To convert 4/5 into a decimal, divide 4 by 5: 4 ÷ 5 = 0.8. Since 0.80 is equal to 0.8, the statement is true.

4. Is 0.55 equal to 11/20?
To convert 11/20 into a decimal, divide 11 by 20: 11 ÷ 20 = 0.55. Since 0.55 is equal to 0.55, the statement is true.

Therefore, in all of the given examples, the decimals are indeed equal to their corresponding fractions.
