How can i tell a fraction is close to 0, 1/2, or 1

The easiest way would be to draw it out. If you've even seen a ruler, it's usually maked with whole numbers, the half mark, and all the numbers in between. You can turn them into a decimal to see where it fits on the number line. For example, divide 3/4. It equals 0.75 which would be closer to one. But say you had the fraction 2/3. Divide it and you get 0.66 which is near 1/2 ( A half is 0.5) but rounds closer to one.
