A notebook is 3/10 off the original price. How could this be written as a decimal? What percentage is the discount?

A decimal: 0.3     A percentage: 30%

Step-by-step explanation:

To calculate the decimal:

3/10=0.3

Three divided by 10 is 0.

After writing the zero put a little dot beside it.

Then you add a little zero to three to make it 30

Then it becomes 30 divided by 10 and the answer is three so the decimal is 0.3

To calculate the percentage:

You can use the decimal. So we say 0.3 multiplied by 100 because a percentage is out of 100.

The answer is 30%
