Rational Number Definition
A number is rational (r) if
it can be expressed as the quotient of two integers, m and n
| r = | m |
| n |
Account for Decimal
Since we have 1 digits to the right of our decimal place,
we multiply 99.7 by 101
99.7 by 101 = 997
997 is our m value
And 10 is our n value
So we have the following ratio:
| 99.7 = | 997 |
| 10 |
Therefore, 99.7 is a rational number
Final Answer
99.7 is rational
