Express 9/10 in simplest form.
mario62 [17]

Answer:

9/10 in simpliest form is 9/10

Step-by-step explanation:

In order to simplify a fraction there must be:

1. A number that will divide evenly into both the numerator and denominator so it can be reduced. No such number exists for 9 and 10.

or

2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 9 is not greater than 10.

9/10 as a decimal: 0.9

9/10 as a percent: 90%
