Rational Number Explorer
Rational numbers ("fractions") are often more difficult to understand than decimal numbers. Use this explorer to get a feeling for them.
Tricky Questions to think about!
How many rational numbers are there between 0 and 1?
What is the smallest rational number which is larger than 0?
How close together can rational numbers get?
Can you always find a rational number between any two decimal numbers?
Can you use this explorer to find a decimal approximation for
