6) a rational decimal can be turned into a fraction, an irrational decimal cannot be turned into a fraction

7) examples and explanations

Rational decimals can become fractions

.50 ( becomes fraction 1/2)
.12 (becomes fraction 12/100)

√25 ( becomes a 5 which is fraction 1/5)

Irrational decimal is a non-terminating, non-repeating decimal

.1234321234 (a non terminating decimal does not become a fraction)

3.14159265359…… (TT pi is non terminating so it cannot become a fraction)

√7 ( becomes 2.6457513110…..non terminating so it is irrational)
